Anionic Copolymerization of Carbonyl Sulfide with Epoxides via Alkali Metal Alkoxides
关键字：carbonyl sulfide, copolymerization, alkali metal alkoxides, sulfur-containing polymer
Carbonyl sulfide (COS), an analogue of carbon dioxide (CO2), can be converted to CO2 via the carbonic anhydride enzymes widely existing in nature. COS is an ideal monomer for making poly(monothiocarbonate)s, which are difficult to synthesize by traditional methods. Herein, for the first time, we describe an anionic copolymerization of COS with epoxides using alkali metal alkoxides as the catalys...

Soluble N-substituted poly(benzimidazole imide)s via C-N coupling reaction
关键字：N-substituted poly(benzimidazole imide)s; heat-resistant polymer; C?N coupling reaction; good solubility
Novelheat-resistantN-substitutedpoly(benzimidazole imide)s (PBIIs)withgoodsolubilitywere synthesized via aC?Ncoupling reaction. A model reaction was carried out to assist in determining the optimal reaction conditions for the polymerization and to elucidate the chemical structures of the polymers. The structures of the resulting polymers were characterized by means of Fourier transform infrared ...

Facile synthesis of heat-resistant and photoluminescent poly(N-aryleneindole ether)s via catalyst-free C–N/C–O coupling reaction
关键字：C-N/C-O coupling reaction; heat-resistant polymer
We present here a novel programmable polymerization route for the synthesis of new indole-based polymers via a catalyst-free nucleophilic substitution reaction. The polycondensation of 4-hydroxyindole with different activated difluoro monomers undergoes in N-methylpyrrolidinone, affording soluble poly(N-aryleneindole ether)s (PEINs) with high molecular weights (Mw up to 486,000) in high yields (...

Synthesis and Characterization of Comb-like Methoxy Polyethylene Glycol-grafted Polyurethanes via ‘Click’ Chemistry
关键字：Polyurethane, ‘Click’ chemistry, comb-like polymer
In this study, a series of comb-likemethoxy polyethylene glycol (MPEG)functionalized polyurethanes (PUs) (PU–g–MPEG)were successfully prepared via ‘click’ chemistry and polyaddition reaction. The copper catalyzed Huisgen 1,3-dipolar cycloaddition was firstly
carried out between 3,5-bis(hydroxymethyl)-1-propargyloxybenzene (PBM) and methoxy polyethylene glycol azide (MPEG–N3) to obta...

(JPS Part A) Poly(vinylphosphonate)s functionalized polymer microspheres via rare earth metal-mediated group transfer polymerization
关键字：fracture; group transfer polymerization; microspheres;
We demonstrate a facile, yet efficient method for the
functionalization of crosslinked polystyrene (PS) microspheres
with biocompatible poly(vinylphosphonate)s via the combination
of a UV grafting polymerization and a surface-initiated group
transfer polymerization. Self-initiated photografting and photopolymerization
of ethylene glycol dimethacrylate results in direct
photografting of poly(ethyle...
