Characteristics of the mechanism of cationic polymerization—I. Copolymerization of the systems α-methylstyrene-styrene ISObutylene-styrene vinyl n-butyl ether-styrene

Polystyrene of high molecular weight was obtained in a good yield by the polymerization of styrene catalyzed by rhenium pentachloride in benzene or benzene—ethylene dichloride solution. The mechanism of this polymerization reaction was studied by kinetic and spectroscopic measurements. Experimental results were well explained by assuming that a π‐complex between rhenium pentachloride and monomer initiates the cationic polymerization in the case of benzene solution and that +CH2CH2Cl initiates the cationic polymerization in the presence of ethylene dichloride.

Rate constants of the propagation and transfer processes for the cationic polymerization of styrene catalyzed by rhenium pentachloride were obtained by kinetic analysis. Also, dependence of the propagation constant on the dielectric constant of the system was examined. Comparison of these data with those of the other systems with different catalysts suggests that the present catalyst is a strong Lewis acid and the size of the counterion is very large.
