The bulk styrene polymerization initiated by dl-diethyl 2,3-dicyano- 2,3-diphenylsuccinate (1) was carried out at 70~90℃. A series of experiments with various initiators such as meso-1, BPO and AIBN, were done. Results showed that the molecular weight of polymers generally increased along with the reaction time under the indicated conditions for all of the initiators. But the molecular weight of polystyrene produced with C---C bond initiators was higher than that initiated by non-C---c bond initiators. The results might be related to the structural features of α-cyano-α- ethoxycarbonylbenzyl radical.
