Abstract
Living polymers endcapped with a silicon containing group can be prepared by reacting a living, anionic polymer with an endcapping agent such as p-(chloromethylphenyl)trimethoxysilane. Such materials possess narrow molecular weight distributions, predictable molecular weights, and high functionality. The functionality is controlled by employing either a monofunctional (f=1) or difunctional (f=2) initiator. The endcapped, unifunctional products of this invention can serve as stable precursors for the preparation of soluble, branched polymers, and the difunctional products of this invention serve as efficient, water curable coatings.
