Abstract
Siloxane copolymers are prepared stepwise by reacting an aminoalkyldiorganoalkoxysilane with a di- or polyisocyanate to form an alkoxysilyl-terminated urea compound, and the urea compound or its reaction product with water is subsequently reacted with a di- or polysilanol-functional polymer to form a copolymer.
