  1. N-alkoxypyridinium salts as coinitiators in radical polymerization: Synthesis and Photochemical Properties

    This article presents an application of N-alkoxy pyridinium salts as coinitiators, sensitized by squaraine to induce a radical curing process. Moreover, a structure-property relationship is constructed by studying the photophysical and electronic properties of some different N-alkoxypyridinium salts, all of which are proposed to accept an electron from the sensitizer to form an oxygen-centered radical that initiates polymerization.

    Remote control grubbs catalysts that modulate ring-opening metathesis polymerizations

    Historically, polymerization catalysts have been designed with predetermined parameters in mind. As such, the choice of catalyst essentially “fixes” the structure and properties of the polymers produced. In contrast, remote control catalysts enable chemists to alter polymerization reactions as they proceed. Due to their high versatility and robustness, the Grubbs-type complexes are ideal for the development of such catalysts. In this highlight, we survey selected Grubbs-type catalysts that have been used to remotely control ring-opening metathesis polymerizations.

  3. Synthesis and utility of ethylene (meth)acrylate copolymers prepared by a tandem ring-opening polymerization hydrogenation strategy

    Sebla Onbulak, Yanzhao Wang, Jacob P. Brutman and Marc A. Hillmyer

    Two functional cyclooctenes are copolymerized using ring opening metathesis polymerization to give the corresponding polyolefin copolymers upon hydrogenation. These materials are used for blend compatibilization and elastomer applications.

    Easy-to-make carboxylic acid dioxythiophene monomer (ProDOT-COOH) and functional conductive polymers

    Daniele Mantione, Nerea Casado, Ana Sanchez-Sanchez, Haritz Sardon and David Mecerreyes

    Version of Record online: 23 JUN 2017 | DOI: 10.1002/pola.28690

    Carboxylic acid functional ethoxythiophene (PRODOT-COOH) monomer has been synthetized and polymerized chemically and electrochemically. This monomer can be used as intermediate to prepare three additional PRODOT monomers via simple condensation with HATU or DCC and electropolymerized to afford functionalized conductive polymers.

  5. Photoresponsive biodegradable poly(carbonate)s with pendent o-nitrobenzyl ester

    Photoresponsive amphiphilic mPEG-b-poly(MNC)n was synthesized via ring-opening polymerization of a six-number cyclic carbonate bearing pendant o-nitrobenzyl group. The morphological changes of the polymer micelles in response to UV light were investigated. The controlled release of loaded NR was demonstrated under UV irradiation. The obtained mPEG-b-poly(MNC) showed good biocompatibility and low toxicity against HepG2 cells and HeLa cells.
