  1. RAFT of sulfobetaine for modifying poly(glycidyl methacrylate) microspheres to reduce nonspecific protein adsorption

    Jana Koubková, Hana Macková, Vladimír Proks, Miroslava Trchová, Jiří Brus and Daniel Horák

    Article first published online: 30 APR 2015 | DOI: 10.1002/pola.27681

    Monodisperse poly(glycidyl methacrylate) microspheres were grafted with zwitterionicpoly{[3-(methacryloylamino)propyl]dimethyl(3-sulfopropyl)ammonimum hydroxide} using RAFT polymerization initiated from the particle surface. Increasing amounts of polysulfobetaine on the surface rendered the microspheres hydrophilic and biocompatible and significantly reduced nonspecific adsorption of bovine serum albumin.

  2. Bioreducible hyperbranched polyglycerols with disulfide linkages: Synthesis and biocompatibility evaluation

    Anionic ring opening polymerization of glycidol and a disulfide-containing epoxide monomer was used for the synthesis of multifunctional and water-soluble disulfide-bearing biodegradable hyperbranched polyglycerols both in the low and high molecular weight range. The polymers were degraded to lower molecular weight polymer fragments in presence of reducing agents such as TCEP, DTT, and glutathione. The polymers also showed excellent biocompatibility profiles even at very high concentrations and could be useful as nanocarriers for intracellular delivery of therapeutics.

  3. Shape memory biomaterials prepared from polyurethane/ureas containing sulfated glucose

    Article first published online: 29 APR 2015 | DOI: 10.1002/pola.27668

    Crosslinked polymers were synthesized using monomers modified with glucose. The polymers showed shape memory behavior. A glass transition temperature of 39 °C, close to physiological temperatures, was obtained. The polymer recovered to the permanent shape when heated to 50 °C. The surface of a film of the polymer can be sulfated to achieve increased blood-compatibility without sacrificing the shape memory properties.

  4. Preparation of microporous polymers in the form of particles and a thin film from hyperbranched polyphenylenes

    Min Chul Cha, Yoonbin Lim and Ji Young Chang

    Article first published online: 29 APR 2015 | DOI: 10.1002/pola.27670

    Thumbnail image of graphical abstract

    A hyperbranched polyphenylene with numerous unreacted bromophenyl end groups was used as a multifunctional building block for the synthesis of a microporous organic polymer. The precursor polymer could be shaped into a film and the subsequent cross-linking reaction produced an insoluble porous film.

  5. Facile and versatile platform for the preparation of functional polyethylenes via thiol-ene chemistry

    Zeyun Xiao, Christopher W. Bennett and Luke A. Connal

    Article first published online: 27 APR 2015 | DOI: 10.1002/pola.27667

    Thumbnail image of graphical abstract

    A modular approach to the preparation of functional polyethylenes is presented. Polycyclooctene polymers are prepared via ring opening metathesis polymerization. The internal alkene bonds of the subsequent polyclycooctenes are exploited using photochemical thiol–ene click chemistry. A range of branched, amphiphilic, and fluorinated polyethylenes are synthesized.
