Patent ID: 7605203

Claim:
A curable polymer composition comprising (a) about 1-99 wt. %, based on total polymer, of a compatiblizer comprising at least one organic polymer having silane groups, the organic polymer having a molecular weight greater than 1000 g/mole and being a polyurethane, polyether, polyester, polycarbonate, polystyrene, styrene butadiene, polybutadiene, butyl rubber, or mixtures thereof, (b) about 1-45 wt. %, based on total polymer, of at least one reactive organopolysiloxane polymer having a molecular weight of about 10,000 to 200,000 g/mole, the reactive organopolysiloxane polymer containing at least one reactive functional group selected from hydroxyl, alkoxy, acyloxy, ketoximo, amino, amido, aminoxy, alkenoxy, alkenyl and enoxy, (c) about 0-98 wt. %, based on total polymer, of at least one silane-free organic polymer having a molecular weight greater than 1000 g/mole, and (d) optionally, up to about 45 wt. %, based on total polymer, of a non-reactive organopolysiloxane.
