Curable isobutylene polymer
摘要:
An isobutylene polymer having at least one silicon-containing group cross-linkable by the formation of a siloxane bond. The isobutylene polymer is a novel polymer curable at ordinary temperature and has not only excellent weatherability, water-resistance and heat-resistance but also excellent electric isolation and gas impermeability.
