Abstract
Abstract Alkali metal terminated organic polymers are reacted with silicon containing compounds having aliphatic unsaturation to produce a new class of reactive silylated organic polymers. These silylated organic polymers can in turn be reacted with cyclic siloxanes to produce silylated organic-organopolysiloxane block copolymers which are useful as protective coatings, surfactants and as elastomers.
