  1. Polymerization of mono-, Di-, and trichloroethyl methacrylates: A study in chain transfer

    Chain transfer to polymer leading to subsequent crosslinking during bulk polymerizations of mono-, di-, and trichloroethyl methacrylate monomers is analyzed by crosslink density characterization, by chain transfer measurements on chloroalkyl model compounds and by model compound deuterium isotope effects. A vicinal effect (chlorine activation of a vicinal hydrogen for abstraction) mechanism is proposed and correlated with chain transfer constant measurements from four series of model compounds.

  2. Optical, electrochemical, and sensing properties of polyfluorenes bearing thiazole or oxazole and triphenylamine in the main chain

    Polyfluorenes containing 4,5-diphenylthiazole or 4,5-diphenyloxazole and triphenylamine (TPA) in the main chain were synthesized. Optical and electrochemical properties depended on the content of TPA in the polymer chain. Polyfluorenes with thiazole or oxazole in main chain are dual fluorescent sensors. They detect Fe2+ with PL quenching mechanism. I ions quench the PL of polymers but the addition of Hg2+ “turn on” the PL of polymer/I.

  3. Redox-responsive core cross-linked micelles of poly(ethylene oxide)-b-poly(furfuryl methacrylate) by Diels-Alder reaction for doxorubicin release

    Redox-responsive core cross-linked (CCL) micelles of poly(ethylene oxide)-b-poly(furfuryl methacrylate) (PEO-b-PFMA) are constructed by reversible addition-fragmentation chain transfer polymerization and Diels-Alder click-type chemistry. The core cross-linking of PFMA blocks is carried out by using dithiobismaleimidoethane at 60 °C without any catalyst. The in vitro drug release profiles present a burst release of doxorubicin at pH 5.0 in the presence of 1,4-dithiothreitol. The cytotoxicity of CCL micelles shows a high antitumor activity towards HepG2 cells.

  4. A facile and controllable synthesis of dual-crosslinked elastomers based on linear bifunctional polydimethylsiloxane oligomers

    A facile and effective strategy for preparing dual-crosslinked supramolecular elastomer is reported. Based on a previously neglected covalent crosslinking reaction during the preparation of supramolecular elastomer based on bifunctional carboxyl-terminated polydimethylsiloxane (PDMS-COOH2), an isocyanate mixture is introduced to cure the precursor into supramolecular elastomer with hybrid crosslinking network. Thus a series of supramolecular elastomers with different covalent crosslink degree can be easily synthesized just by adjusting the composition of curing agent.

  5. Synthesis of reduction sensitive comb-like polyurethanes using click chemistry

    The preparation of comb-like polyurethanes is carried out from a number of multipropargyl copolyurethanes and their subsequent derivatization via alkyne–azide click reaction with chemically-diverse azides. A straightforward method, based on TGA experiments, is highlighted to qualitatively track the success of the derivatization processes. A wide variation in degradability under physiological conditions of the new comb-like PU can be attained simply by adjusting the chemical structure of the polymer to synthesize.
