摘要

New siloxane copolymers having vinyloxy groups contain: (a) siloxane units having the formula (I): RaSi(OR<1>)bO(4-(a+b))/2, (b) at least one unit per molecule selected among the group of units having the formula (II): GRcSiO(4-(c+1))/2, G = -CH2CH2OY(OCH=CH2)x-1, and (c) at least one unit per molecule having the formula (VI), in which R, R<1>, R<2>, Y, Z, a, b, c, u, x and y have the meaning given in the first claim.
