摘要: The bulk polymerization of styrene (St) initiated with a hexa-substituted-ethane type initiator, diethyl 2,3-dicyano-2,3-diphenylsuccinate (DCDPS), was investigated. It was found that DCDPS served as a thermal iniferter for polymerization of St and the polymerization had some characteristics in common with living radical polymerization, ie, both the yield and the molecular weight of the resulting polymers increased with increasing reaction time. The resultant polystyrene can act as a macroinitiator for chain-extension polymerization of St or for radical polymerization of methyl methacrylate to give a block copolymer.
