Vinylamide oligomers and lower molecular weight polymers are prepared by the cationic polymerization of vinylamides in the presence of a Lewis acid at a temperature between -100.degree. and 100.degree. C. The resultant vinylamide oligomers and polymers can optionally be hydrolyzed under acidic or basic conditions to form the corresponding vinylamine oligomers and polymers.
