<P>PROBLEM TO BE SOLVED: To provide a thermoplastic roofing membrane including the particles of crosslinked rubber and an aqueous (co)polymer dispersion. Ž<P>SOLUTION: The thermoplastic roofing membrane is formed by combining particles of crosslinked rubber and a suspension polymer dispersion or a coagulated aqueous latex (co)polymer dispersion, to form a mixture in aqueous dispersion, which aqueous dispersion mixture is subjected to solid state shear pulverization to form a material that can be processed as thermoplastics at a crosslinked rubber concentration of from 10 wt.% to as high as 95 wt.%, based on the total solid of the material. The method may further comprise kneading the pulverized product, followed by extrusion to form the roofing membrane. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
