Abstract

Cationic copolymerization of trioxane with glycidyl ester derivatives, preferably glycidyl acrylate derivatives, produces thermally stable, usually cross-linked, acetal copolymer. The resulting acetal copolymer will exhibit side chain ester functionality, and particularly side chain vinyl functionality when glycidyl acrylate derivatives are employed, so as to permit its futher reaction with other chemical moieties to achieve an acetal copolymer of modified chemical and/or physical properties.
