英文摘要 | 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(Mw/Mn=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.; Living radical polymerization of methyl methacrylate was investigated using a new initiation system, i. e.
