Abstract : The polymerization of N-vinylcarbazole catalyzed by strong and weak Bronsted acids, diethylchlorophosphate and other compounds which hydrolyze to yield Bronsted acids, was studied under various reaction conditions in acetonitrile and methylene chloride as solvents. The polymerization is unaffected by oxygen and carbon dioxide. Although formulation of a rate expression remains inconclusive, it is evident that the cationic polymerization of N-vinylcarbazole has unusual features which facilitate a unique susceptibility to catalysis by low concentrations of acids, e.g. 40 parts per billion. The feasibility of selective sensitization to catalysis of interest was demonstrated.
