摘要：A bromine capped polystyrene (PS-Br) with an M-n of around 5,000 was synthesized by using Cu(phen)(2)Br/1-PEBr as catalyst and initiator to polymerize styrene (St) according to atom transfer radical polymerization (ATRP) mechanism. Then, by using such a PS-Br as a macro-initiator, some block copolymers [P(St-b-MMA) and P(St-b-BA)] were also prepared through phen-ATRP. These block copolymers have been characterized by means of GPC, IR,H-1-NMR and DSC, respectively. It was found chat there were no any homopolymers in these block copolymer systems and P(St-6-BA) exhibited a compatible system due to the short length of both blocks,although the miscibility between these two blcoks was poor. By using phen/CuCl/RCl as catalyst and initiator, the explosive polymerization phenomenon of methacrylate (MA) was observed. However,the copolymerization of MA and iso-butyl vinyl ether (IBVE) could be controlled in ATRP. The obtained poly(MA-co-IBVE) was characterized and discussed by using DSC and H-1-NMR.
