ABSTRACT:
Vinylamide oligomers having molecular weights between about 280 and 7,500 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 are characterized in that they have a proton initiating group at one end and an aldehyde equivalent at the other end. These vinylamide oligomers can optionally be hydrolyzed under acidic or basic conditions to form the corresponding vinylamine oligomers.
