Abstract:
    The capping of anionic polymers to make functionalized polymers is improved by using alkoxy silyl compounds having protected functional groups, such as acetal groups, as the capping agent. The protected functional groups are stable under a variety of conditions and then readily convert to more reactive terminal functional groups useful for making adhesives, sealants and coatings.
