原子转移自由基聚合合成耐热性共聚物
ynthesis of Heat-resistant Copolymers by Atom Transfer Radical Polymerization
摘要
Abstract
Atom transfer radical copolymerization (ATRP) of styrene (St) and N-cyclohexylmaleimide (NCMI) with the CuBr/bpy catalyst in anisole, initiated by 1-phenylethyl bromide(1-PEBr) or tetra(bromomethyl)benzene(TBMB), afforded well-defined copolymer with predetermined molecular weights and low polydispersities, Mw/Mn < 1. 5. Other monomer pairs such as methyl methacrylate (MMA)/NCMI, St/N-phenylmaleimide, MMA/N-phenylmaleimide were studied, too. The influences of several factors, such as temperature, solvent and monomer's ratio on the copolymerization with the CuBr/bpy catalyst system were subsequently investigated. The apparent activation energy of St (MMA)and NCMI was deduced from the kinetics figure of different temperatures. Using TBMB as the initiator produced four-armed star copolymer. The heat resistance of the resultant copolymer has been improved by increasing the NCMI.关键词
