    Soft tissue in biological system is a hydrogel with elaborate structure exhibiting repeatable dynamic function. In order to approach such sophisticated system, precise construction of a designed network with multi‐components is desired. This communication presents a novel hydrogel having highly dense stimuli‐responsive free‐end chains around crosslinking structure. A key molecule is a core‐crosslinked star‐shaped polymer with multiple thermoresponsive arms, which can be prepared by reversible addition–fragmentation chain transfer polymerization of divinyl crosslinker with poly(N‐isopropylacrylamide) (PNIPAAm) macro‐chain transfer agent and have a number of unreacted carbon–carbon double bonds in the core. These unreacted double bonds can be utilized as a crosslinker for poly(acrylamide) (PAAm) gel synthesis by free radical polymerization. The obtained gel contains homogeneously dispersed star PNIPAAms as crosslinking points and exhibits thermoresponsive swelling behavior in water depending on the star contents. In particular, the gel with low content of the star crosslinker shows localized responsive behavior with expansion and shrinkage of the star in one molecule. The mechanical properties of the star‐crosslinked gel are significantly high compared to the conventional PAAm gels particularly in compressive strength (≈9 MPa). Moreover, the star‐crosslinked gel has thermoresponsive mechanical toughening property.

    A deep understanding of the effect of the ionic density in a polymer on the solution properties would contribute to the development of novel stimuli-responsive materials. To this end, a multibranched and highly dense structure is an attractive platform for the accumulation of ionizable groups. In this study, we focus on core-crosslinked multiarm star polymers having ionizable poly(acrylic acid) (PAA) segments in the arms with different sequences to evaluate the density effect of ionic segments on pH-responsive properties. Two types of star polymers with a PAA block on the outer or inner side of an arm chain in combination with a hydrophilic poly(2-hydroxyethyl acrylate) (PHEA) block were synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. These star polymers exhibited aggregation behavior different from the corresponding linear block polymer in an acidic aqueous solution. Dynamic light scattering analysis in water revealed that the star polymer with PAA in the outer layer formed larger aggregates than the star polymer with the inverse layer structure, and the pH-responsive change of the hydrodynamic radius in water depends on the sequence in the arm polymers. This behavior resulted from the balance of hydrogen bonding between PAA and PHEA segments and PAA electrostatic repulsion.

    We designed a hydrogel with a thermoresponsive crosslinked domain (CD) structure, which expressed thermoresponsive toughening in an isochoric manner in air. The responsive behavior of conventional thermoresponsive hydrogels is usually a macroscopic volume change along with water transfer to and from the outside of the polymer network. In order to expand the scope of thermoresponsive hydrogels, a network design that requires no external water for thermoresponsive transition has been demanded. To this end, we focused on the polymerization-induced self-assembly process for the direct synthesis of gels with designed domains and performed reversible addition-fragmentation chain transfer polymerization of N-isopropylacrylamide in water at a high temperature using a bifunctional macro-chain transfer agent, yielding a transparent gel. The structural analysis of the obtained gel revealed that dispersed CDs reversibly swelled and shrunk in response to temperature change in air without aggregation. Such an internal structural change induced the increase of elastic modulus and elongation at a high temperature.

    © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Thermoresponsive polymers in water, for example, poly(N-isopropylacrylamide) (PNIPAM) are investigated extensively, due to a wide range of biomedical applications. However, the attempts to control thermoresponsiveness are still rare in less or nonpolar media. Herein, the three thermoresponsive homopolymers tethering an N-butylurea group in the side chain with a different polymer backbone are reported. They exhibit lower critical solution temperature (LCST)-type and upper critical solution temperature (UCST)-type thermoresponsiveness depending on association of the urea group in the polymer chain and hydrogen bonding small molecules (effectors) in ternary systems (polymer/effector/organic solvent). The difference of polymer backbone appears as their change of solvophobicity in organic solvents. Poly(methacrylate) backbone needs more amount of the effector in nonpolar organic solvents, and poly(vinyl ether) backbone needs more amount in polar organic solvents. However, the influence of polymer backbone is too little to change the phase transition behavior, and the thermoresponsiveness is dominated by association and dissociation of hydrogen bondings between polymers and effectors. The supramolecular design of the thermoresponsive polymers is strong and extensible for the design of their phase transitions.

    © 2019 The Royal Society of Chemistry. Thermoresponsive alternating, block, and gradient-like copolymers with acid-degradability were synthesized via controlled cationic copolymerization of conjugated aldehydes and vinyl ethers (VEs). The thermoresponsive behavior of the resultant copolymers in water was governed by the polymer sequence. For example, an alternating copolymer was soluble in water at low temperature and displayed a sharp one-step phase separation on heating. By contrast, a block copolymer consisting of a degradable alternating sequence and a VE homosequence exhibited two-step phase separation in water. The alternating copolymers contained acid-labile acetal linkages in the main chain at periodic intervals and thus decomposed rapidly into small molecules without residual oligomers under acidic conditions. The block and gradient-like copolymers were hydrolyzed into VE polymers and oligomers, respectively, due to the presence of non-degradable VE-VE linkages. The thermoresponsive patterns of the hydrolysis products differed from those of the original polymers.

    © 2019 The Royal Society of Chemistry. Various ligands were screened for the cationic polymerization of isobutyl vinyl ether (IBVE) via in situ complexation using ZrCl4 as a catalyst precursor. [N,O]-Type phenoxyimine ligand frameworks were found to be more efficient for controlled polymerization compared to ligands that coordinate to the metal via two oxygen ([O,O]-type ligands) or two nitrogen ([N,N]-type ligands) atoms. In particular, the N-aryl phenoxyimine ligand with tBu groups on the phenol moiety was effective in terms of the controllability of the polymerization, catalyst solubility, catalytic activity, and ease of derivatization. Moreover, optimization of reaction conditions led to the expansion of the applicable metal species for controlled cationic polymerization. The polymerization of IBVE using the N-phenyl phenoxyimine ligand/TiCl4 initiating system in the absence of ethyl acetate in toluene at -78 °C produced a well-controlled polymer. In addition, the phenoxyimine/ZrCl4 systems were effective for the controlled polymerization of various monomers including St derivatives. The easily tunable electronic properties were also useful for the controlled bulk polymerization.

    © 2019 Elsevier B.V. Chitosan/calcium carbonate core-shell type composite microparticles were fabricated via a biomineralization-inspired process with chitosan particles as starting materials. The obtained composite particles were spherical, and the diameter of the composite particles was larger than that of the chitosan particles. XRD measurement indicated that the shell of the composite particle had a crystalline structure. The shell fabrication process was carried out with polyacrylic acid (PAA) or polyglutamic acid (PGlu) as binder molecules between calcium carbonate and chitosan. The crystal form of the shell fabricated with PAA was calcite, which is the most stable form of calcium carbonate crystal. On the other hand, the shell fabricated with PGlu was composed mainly with vaterite crystal, which is not a stable form. Types of the binder molecules influenced the crystal structure of the calcium carbonate shell. Drug release behavior of the model drug-introduced core-shell particles was evaluated in various pH conditions. It was revealed that the inorganic shell suppressed drug release and that the crystal form of the calcium carbonate shell affected suppression of drug release. The core-shell particles prepared in this study was an environmentally friendly hybrid product consisting of inorganic and organic materials and could be used as a novel drug-carrying microcapsule.

    © 2018 Wiley Periodicals, Inc. Controlled cationic polymerization of trans-1-methoxy-1,3-butadiene was achieved through the design of appropriate initiating systems, yielding soluble polymers with controllable molecular weights. The combined use of SnCl4 or GaCl3 as a Lewis acid catalyst and a weak Lewis base in conjunction with HCl as a protonogen resulted in efficient and controlled polymerization. The Mn values of the product polymers increased linearly along the theoretical line, which indicates that intermolecular crosslinking reactions negligibly occurred. In addition, the polymer microstructure was critically dependent on the weak Lewis base employed. In particular, the use of tetrahydrofuran as an additive resulted in the highest 4,1/4,3-structure ratio (96/4). Weak Lewis bases also affected the polymerization rates but exhibited unique trends that differed from their effects on the cationic polymerization of alkyl vinyl ethers. © 2018 Wiley Periodicals, Inc.

    © 2019 Wiley Periodicals, Inc. We investigated the cationic polymerization of vinyl ethers using metal complex catalysts with salen and salphen ligands. Metal complexes were generated in situ from the reaction of a ligand and a metal chloride. The choice of a ligand and a central metal was crucial for tuning the catalyst function such as catalytic activity and controllability of the polymerization. Among metal chlorides employed, ZrCl 4 was the most efficient for controlled polymerization. Cationic polymerization of isobutyl vinyl ether (IBVE) proceeded using the salen and salphen-type ligand/ZrCl 4 initiating systems, yielding polymers with predetermined molecular weights and narrow molecular weight distributions. Importantly, the structural effects of the complex catalysts were responsible for the polymerization behavior. For example, the polymerization using the salen-type ligand/ZrCl 4 system was much slower than that using the salphen-type ligand/ZrCl 4 system. In addition, the polymerization of IBVE using the salen-type ligand/FeCl 3 system proceeded in a controlled manner, which was in contrast to uncontrolled polymerization using the salphen-type ligand/FeCl 3 system. © 2019 Wiley Periodicals, Inc.

    © 2019 Wiley Periodicals, Inc. The catalyst structure–property relationships of the phenoxyimine complexes in controlled cationic polymerization of vinyl ethers were investigated based on the Hammett correlation. The correlation analyses of a series of experiments using the phenoxyimine ligands/TiCl4 initiating systems indicated that the substituents on the N-aryl phenoxyimine ligands affected the polymerization rate and stereoselectivity. Importantly, a linear correlation was observed between the Hammett substituent constants and the polymerization rates, which indicates that the Lewis acidity of the complex is affected by the electron-withdrawing and -donating effects of the substituents. The tacticity of product polymers correlated to the Hammett substituent constants. Unlike the relationship with the polymerization rates, the σ– values, which account for the enhanced resonance effects, were more appropriate for the relationship with the tacticity than the normal σ values. In contrast, the polymerization behavior using o-substituted ligands exhibited a trend different from those using p- or m-substituted ligands. The structural change, which was caused by the rotation of the CN bonding, most likely triggered the acceleration effect in the case of the o-substituents. © 2019 Wiley Periodicals, Inc. J. Polym.

    © 2018 American Chemical Society. A new class of polylactide (PLA)-based block copolymers with thermoresponsive poly(vinyl ether) [poly(VE)] were precisely synthesized via successive living cationic polymerization of VE and ring-opening polymerization of lactide (LA). The synthetic route starts with precise end-functionalization of poly(VE) by living cationic polymerization to produce a macroinitiator having a hydroxy group at the α- and/or -end for ring-opening polymerization of LA. End-functionalized polymers of 2-methoxyethyl VE (MOVE) with highly controlled structures were obtained by either an initiation or a termination method under optimized conditions. Subsequent ring-opening polymerization of LA from the hydroxy group of the macroinitiator yielded block copolymers with well-defined structures. The obtained block copolymers were demonstrated to exhibit a thermoresponsive solubility transition in water; this transition was induced by the thermosensitivity of the poly(MOVE) segments. The transition between micelle-like aggregates and phase separation was reversible with a shorter PLA chain, whereas irreversible precipitation was observed with a longer PLA segment. The permanent precipitation upon heating is most likely attributable to crystalline formation of the longer PLA segments. The solution and bulk properties of the block copolymers with enantiomeric PLA were also governed by stereocomplex formation between poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) segments.

    © 2018 American Chemical Society. The synthesis of well-defined graft copolymers with designed intervals between branches was achieved using cyclic acetal moieties as two-stage latent initiating sites. A cyclic acetal was shown to initiate the living cationic polymerization of vinyl ethers (VEs), yielding a polymer with a hydroxy group at the α-end derived from the cyclic acetal. The newly generated hydroxy group was able to efficiently induce the subsequent ring-opening anionic polymerization of l-lactide (LLA), and a diblock copolymer with a narrow molecular weight distribution (MWD) was obtained. For the synthesis of a graft copolymer, a five-membered cyclic acetal moiety was introduced at the ω-chain ends of poly(VE)s, which was employed as the initiating site for the living cationic polymerization of VEs. Repeated polymerization and acetalization generated a macroinitiator with several hydroxy groups on the side chain of a poly(VE) backbone. Graft copolymers possessing branches with narrow MWDs and regular spaces between the branches were synthesized by the ring-opening polymerization of LLA using this macroinitiator.

    © 2018 by the authors. In this study, we investigated the aggregation behaviors of amphiphilic poly(vinyl ether)s with antimicrobial activity. We synthesized a di-block poly(vinyl ether), B3826, composed of cationic primary amine and hydrophobic isobutyl (iBu) side chains, which previously showed antimicrobial activity against Escherichia coli. B3826showed similar uptake behaviors as those for a hydrophobic fluorescent dye, 1,6-diphenyl-1,3,5-hexatriene, to counterpart polymers including homopolymer H44 and random copolymer R4025, indicating that the iBu block does not form strong hydrophobic domains. The cryo-TEM observations also indicated that the polymer aggregate of B3826appears to have low-density polymer chains without any defined microscopic structures. We speculate that B3826formed large aggregates by liquid-liquid separation due to the weak association of polymer chains. The fluorescence microscopy images showed that B3826bonds to E. coli cell surfaces, and these bacterial cells were stained by propidium iodide, indicating that the cell membranes were significantly damaged. The results suggest that block copolymers may provide a new platform to design and develop antimicrobial materials that can utilize assembled structures and properties.

    © 2017, The Society of Polymer Science, Japan. Degradable alternating copolymers with distinctly fluorous characteristics were synthesized via controlled cationic copolymerization of perfluoroalkyl vinyl ethers (VEs) and conjugated aldehydes. Well-defined alternating copolymers were obtained using the EtSO3H/GaCl3 initiating system in the presence of 1,4-dioxane as an added base and 2,6-di-tert-butylpyridine as a proton trap in a fluorine solvent at -78°C. Various conjugated aldehydes and fluorine-containing VEs were also investigated for controlled alternating cationic copolymerization. The solubility of the obtained alternating copolymers improved compared to the fluorine-containing VE homopolymer. In particular, copolymers underwent upper critical solution temperature-type phase separation behavior in various solvents. In addition, polymer thin films of the alternating copolymers exhibited high water and oil repellency. All alternating copolymers were decomposed into small molecules under an acidic condition without residual oligomers in both solution and thin film state.
