ABSTRACT:
A high yield of three armed radial anionic polymers is produced by the process of coupling metal terminated anionic polymers with a trialkoxysilane having a silicon-hydrogen bond, preferably trimethoxysilane. The metal terminated anionic polymer is preferably produced by initiating polymerization with a protected functional initiator which is readily converted to terminal hydroxyl groups or derivatives thereof for use in adhesives, sealants, and coatings.
