【Abstract】 Living radical polymerization of methyl methacrylate was investigated using a new initiation system, i. e. DCDPS/Fe(DC) 3, in which diethyl 2,3 dicyano 2,3 diphenyl succinate(DCDPS) is a hexa substituted ethane thermal iniferter and ferric tri(diethyldithiocarbamate)(Fe(DC) 3) is a ligand free catalyst. The polymerization was successfully controlled in bulk at 95 ℃, PMMA with high molecular weight and quite narrow polydispersities( M w/ M n=1 20~1 29) were obtained. End group analysis by 1H NMR spectroscopy shows that the resulting PMMA is ω functionalized by a DC group.更多还原
