Abstract: Carbocationic polymerization of isobutylene was initiated by the system of diethyl aluminium chloride/benzyl chloride/pyridine.It was found that in the presence of electron donor (pyridine), the initiator efficiency increased and the molecular wieght distribution of the polymers narrowed.The linear relationship between the molecular weight and amount of poly-isobutylene which was prepared by the increment monomer addition experiment, and its amount showed that the polymerization got some living features.

Key words: Isobutylene, Carbocationic polymerization, Initiator, Diethyl aluminium chloride, Electron donor
