PROBLEM TO BE SOLVED: To provide a method for producing composite materials from crosslinked rubber and coagulated aqueous polymer dispersions. SOLUTION: This method for producing composite materials comprises blending particles of crosslinked rubber with coagulated aqueous polymer dispersions to form a mixture in an aqueous dispersion, and subjecting the aqueous dispersion mixture to solid state shear pulverization to form material that can be processed as a thermoplastic at crosslinked rubber concentration of from 10 to 95 wt.%, based on the total amount of solids of the material. The method may further comprise kneading the pulverized product to form useful articles, such as roofing members and shoe soles. COPYRIGHT: (C)2010,JPO&INPIT
