Abstract: The paper reported a novel method to control termination of isobutylene cationic polymerization, which can be called the transformation of reactive end(TRE).The reactive center of isobutylene propagation was completely transformed to stable diphenyl alkyl cation at 80℃ by reaction with 1,1-diphenyl ethylene,The end of one polymer chain was capped with only one DPE molecule no matter how amount of DPE was excess or equal to that of initiator.The product contained special double bond at the chain end.Model initiator, which was model of such cation initiated polymerization of isobutyl vinyl ether successfully.

Key words: Isobutylene, Cationic polymerization, Transformation of reactive end
