ABSTRACT:
This invention relates to alkenyl ether functional polyisobutylenes. This invention also relates to a method of making alkenyl ether functional polyisobutylene polymers comprising reacting a mixture comprising an alkoxysilyl-functional polyisobutylene polymer, an alkenyl ether compound, and a transesterification catalyst. This invention also relates to a method of making an alkenyl ether functional polyisobutylene polymer comprising reacting a mixture comprising a polyisobutylene containing at least one hydrolyzable group, an alkenyl ether compound, and a solvent. The alkenyl ether functional polyisobutylenes of this invention have high moisture vapor barrier, high damping characteristics, and a high refractive index.
