Synthesis, characterization, and thin‐film properties of 6‐oxoverdazyl polymers prepared by ring‐opening metathesis polymerization

19-Jan-2016 | Joseph A. Paquette, Sabastine Ezugwu, Vishal Yadav, Giovanni Fanchini, Joe B. Gilroy, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Redox‐active 6‐oxoverdazyl polymers were synthesized via ring‐opening metathesis polymerization (ROMP) and their solution, bulk, and thin‐film properties investigated. Detailed studies of the ROMP method employed confirmed that stable radical polymers with controlled molecular weights ...

Solution polymerization of polybenzimidazole

16-Jan-2016 | Kayley J. Fishel, Alexander L. Gulledge, Andrew T. Pingitore, Jason P. Hoffman, Warren P. Steckle, Brian C. Benicewicz, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Polybenzimidazoles (PBI) are an important class of heterocyclic polymers that exhibit high thermal and oxidative stabilities. The two dominant polymerization methods used for the synthesis of PBI are the melt/solid polymerization route and solution polymerization using polyphosphoric ...

Synthesis of pH‐ and thermoresponsive poly(2‐n‐propyl‐2‐oxazoline) based copolymers

05-Jan-2016 | Marcel A. Boerman, Harry L. Van der Laan, Johan C. M. E. Bender, Richard Hoogenboom, John A. Jansen, Sander C. Leeuw ..., Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Polymers that possess lower critical solution temperature behavior such as poly(2‐alkyl‐2‐oxazoline)s (PAOx) are interesting for their application as stimulus‐responsive materials, for example in the biomedical field. In this work, we discuss the scalable and controlled synthesis of a ...

Emulsion copolymerization of substituted acetylenes for constructing optically active helical polymer nanoparticles. Synergistic effects and helicity inversion

05-Jan-2016 | Biao Zhao, Jianping Deng, Wantai Yang, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Copolymerizations of substituted acetylenes have been intensively studied in solution polymerization for constructing chirally helical polymers, while emulsion copolymerizations of the kind of monomers have been only scarcely reported. In the present study, chiral substituted ...

Vinyl phenylboronic acid controlling co‐monomer for nitroxide mediated synthesis of thermoresponsive poly(2‐N morpholinoethyl methacrylate)

18-Dec-2015 | Xeniya Savelyeva, David Chondon, Milan Marić, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT Low concentrations of 4‐vinylphenylboronic acid (VPBA) were copolymerized with 2‐N‐morpholinoethyl methacrylate (MEMA) by nitroxide mediated polymerization using BlocBuilder™ unimolecular initiator at 80 to 90 °C. The MEMA/VPBA copolymerizations were performed at initial feed ...
