Abstract Lifetime of the propagating species and initiation rate constants (ki) were evaluated for the cationic polymerization of p-methoxystyrene initiated by I2, CH3SO3H, BF3O(C2H5)2, and SnCl4. The lifetime was found to be fairly long, ranging from 0.2 to several seconds in 1,2-dichloroethane at 30°C; that for the intermediate generated by iodine (2–6 s) much exceeded the others. The ki value increased in the order: I2 〈 CH3SO3H ≪ BF3O(C2H5)2 ∼ SnCl4.
