  1. Synthesis, characterization, and photovoltaic properties of dithienylbenzobisazole-dithienylsilole copolymers

    Achala Bhuwalka, Monique D. Ewan, Jared F. Mike, Moneim Elshobaki, Brandon Kobilka, Sumit Chaudhary and Malika Jeffries-EL

    Article first published online: 28 MAR 2015 | DOI: 10.1002/pola.27603

    Three donor-acceptor copolymers based on a donor-acceptor-donor triad of either cis-benzbisoxazole, trans-benzobisoxazole or trans-benzobisthiazole and dioctyl-dithieno-[2,3-b:2',3'-d]silole were synthesized. The impact of these structural modifications on the optical, electrochemical, and morphological properties of the polymers were investigated. The performance of these copolymers in photovoltaic cells is also reported.

  2. Synthesis of dual-functional poly(6-azidohexylmethacrylate) brushes by a RAFT agent carrying carboxylic acid end groups

    A novel dual-functional surface-attached polymer brush was synthesized by an interface-mediated RAFT polymerization. This interface-mediated RAFT polymerization produced silicon substrate coated with dual-functional (azido groups from monomer and carboxylic acid groups from RAFT agent) poly(6-azidohexylmethacrylate) [poly(AHMA)] brush with a grafting density as high as 0.59 chains/nm2. The azido groups of the poly(AHMA) brushes can be modified with alkyl groups via “CuAAC” click reaction, while the carboxylic acid end groups can be reacted with amine groups via amide reaction.

    Synthesis of polyacrylonitrile mediated by manganese(III) acetylacetonate (Mn(acac)3) and 2-cyanoprop-2-yl dithionaphthalenoate

    PAN was successfully synthesized with Mn(acac)3 as the initiator, and CPDN as the CTA. The novel polymerization complied with a typical RAFT polymerization mechanism. The initial radicals was produced via pyrolysis of Mn(acac)3. Compared with that initiated by AIBN, the polymerization showed better "living"/controlled features with Mn(acac)3 as the initiator.

  4. Functional dye as a comonomer in a water-soluble polymer

    An antimicrobial dye Rose Bengal has been incorporated into a water-soluble copolymer to achieve effective and durable properties. The final product has been characterized from aspects of the percentage of free dye percentage, solubility, and singlet oxygen production rate, which indicates an effective approach to make low cost, sustainable, and durable antimicrobial products by applying this polymer solution to various surfaces.

  5. Synthesis and copolymerization of oligo(lactic acid) derived norbornene macromonomers with amino acid derived norbornene monomer: Formation of the 3D macroporous scaffold

    Sutthira Sutthasupa, Fumio Sanda, Kajornsak Faungnawakij and Puttinan Meepowpan

    Article first published online: 28 MAR 2015 | DOI: 10.1002/pola.27604

    Ring-opening metathesis copolymerizations of amino acid and (oligo)lactic acid-derived novel norbornene monomers using the Grubbs 2nd generation catalyst proceeded satisfactorily. The 3D porous polymer samples were obtained by drying of the polymers under reduced pressure. The average pore sizes of the copolymers increased as the ratios of (oligo)lactic acid unit increased. The copolymers showed higher mechanical strength than the homopolymers, presumably due to enhancement of the intermolecular hydrogen bonding between the amide groups and/or the hydroxy/ester groups.
