FUNCTIONAL COPOLYMERS OF ISOBUTYLENE AND ACRYLIC ESTER

Reactive copolymers of isobutylene and acrylic ester were successfully synthesized by the incorporation of acryloyl chloride or maleic anhyd ride into alternating copolymers of isobutylene and acrylic ester by m eans of complexed copolymerization catalysed with alkylboron halide. T he terpolymers of isobutylene, acrylic ester and acryloyl chloride (AI LM) and isobutylene, acrylic ester and maleic anhydride (AIHM) reacted with many compounds. Via the polymer reactions based on AILM and AIHM , various functional copolymers of isobutylene and acrylic ester were synthesized, which contained carboxyl group, amide group, hydroxyl gro up, nitrile group, epoxy group and so forth on the pendant of the poly mer chains.
