ABSTRACT:
Carbanion containing organic polymers are reacted with silicon containing compounds having aliphatic unsaturation to form a new class of carbanion containing silylated organic polymers. These carbanion containing silylated organic polymers can then be reacted with cyclic siloxanes to form silanoate containing silylated organic-organopolysiloxane block copolymers which may then be reacted with a compound which will react with the carbanion or silanoate to form silylated copolymers and silylated organic-organopolysiloxane block copolymers.
