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...

Preparation of Fluorescent Conjugated Polymer Films with Different Emission Colors: Investigation into the Influences of Chemical Structure and Morphology
关键字：chemical structures，conjugated polymers，films，fluorescence，morphology
A series of PPV fi lms with different fl uorescent emission colors are prepared using a facile approach. Modifi ed from the conventional Wessling route, the labile sulfonium groups in the polymer precursor (pre-PPV) are partly substituted to various degrees by relatively stable methoxy groups, followed by a regular thermal elimination step to obtain PPV. Different chemical structures among these...
