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 ℃, PMMAwith high molecular weight and quite narrow polydispersities( Mw/Mn=1.20-1.29) were obtained. End group analysis by 1HNMRspectroscopy shows that the resulting PMMAis ω-functionalized by a DC group.

Key words: Living radical polymerization, A new initiation system, Diethyl 2,3-dicyano2,3-diphenylsuccinate, Methyl methacrylate
