Abstract

Methods are disclosed for the blending of inherently incompatible polymer systems to provide compositions comprising (i) 1 to 99.99 percent by weight of a diorganopolysiloxane; and (ii) 0.01 to 99 percent by weight of an organopolysiloxane-grafted rigid linear aromatic polymer selected from the group consisting of organopolysiloxane-grafted polyimide and organopolysiloxane-grafted polybenzobisoxazole.
