PMMA-PLA-PMMA三嵌段共聚物的制备
Synthesis of poly ( methyl methacrylate ) -poly ( lactic acid) -poly (methyl methacrylate) tri-block copolymer
摘要
Abstract
Poly( methyl methacrylate)-poly (lactic acid)-poly ( methyl methacrylate) tri-block copolymer was prepared using bromize poly ( lactic acid) as the initiator via atom transfer radical polymerization (ATRP). The effects of n( MMA)/n( Br-PLA-Br) on molecular weight were investigated. Results showed that the first-order plot and a narrow molecular weight distribution followed the characteristics of the ATRP , indicating a controllable polymerization. The glass transition temperature and initial decomposition temperature of the copolymer were well improved by copolymerization, thus it had a potential application in plastic industry.关键词
