Abstract

N-chlorocarbonyl dibenz[b,f]azepine in conjunction with AgSbF6 initiated the cationic polymerization of alpha-methylstyrene in methylene chloride. Polymer samples obtained this way contained terminal dibenzazepine units. Chain extension occurred upon irradiating these polymers with u.v. in benzene solution containing benzophenone or benzil, via cyclobutane formation.
