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...

Progress on High Performance Polymers Bearing Phthalazinone Moieties and Their Applicaion Technologies
关键字：high performance polymer, poly(aryl ether)s, phthalazinone, thermoplastic composites
Rising oil price and pressure to reduce emission push aerospace Original Equipment Manufacturers (OEMs) to use more and more polymer matrix composites (PMC) to reduce weight.Secondly, OEMs also try their best to reduce cost. They keep their eyes on improving repair and maintenance of PMC. Thermoplastics possess excellent comprehensive performance. First of all,OEMs prefer their high toughness,...

(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...

Antibacterial and hemocompatibility switchable polypropylene nonwoven fabric membrane surface
关键字：antibacterial, UV-induced graft polymerization, polypropylene nonwoven fabric membrane, hemocompatibility, zwitterionic polymer
In this article, a facile approach to fabricate a biofunctional polypropylene nonwoven fabric membrane (PP NWF) with a switchable surface from antibacterial property to hemocompatibility is presented. In the first step, a cationic carboxybetaine ester monomer, [(2-(methacryboxy) ethyl)]-N,N-dimethylamino-ethylammonium bromide, methyl ester (CABA-1-ester) was synthesized....

聚合物刷接枝新方法与润滑研究
关键字：polymer brushes，ATRP，lubrication
Surface-initiated controlled radical polymerizations (SIP) from initiator-modified surfaces lead to polymer brushes with variable compositions, architectures and functionalities, as well as complex (co)polymers and organic/inorganic hybrid materials. Among the different controlled radical polymerization techniques, atom transfer radical polymerization (ATRP) is widely used for tailoring the su...
