The ring-opening, nucleophilic addition of amine-terminated oligomers to alkenyl azlactones was exploited to prepare reactive, that is, in free radical polymerizations, oligomers that could be used in 100% solids resin systems. Acrylamide-functional oligomers resulted from the reaction that used 2-vinyl-4,4-dimethylazlactone, whereas methacrylamide-functional oligomers were produced with 2-isopropenyl-4,4-dimethylazlactone. The overall reaction took place under mild conditions, for example, a few hours at room temperature, and was particularly free of side reactions. Examination of reaction rates with the two alkenyl azlactones revealed that the 2-vinyl derivative reacted ca. four times faster. The (meth)acrylamide-terminated resins were characterized by IR, NMR, and molecular weight analyses.
