Abstract
A method for forming blends of polydiorganosiloxanes and solid, sulfonated polyolefins and novel blends prepared by the method. In the present method the solid, sulfonated polyolefin is swollen with a diorganosiloxane oligomer whose rearrangement to high molecular weight polydiorganosiloxanes is catalyzed in situ by the sulfonic acid substituents of the polyolefin.
