Abstract
The present invention provides methods of making composite materials comprising combining particles of crosslinked rubber with coagulated aqueous polymer dispersions to form a mixture in aqueous dispersion, and subjecting the aqueous dispersion mixture to solid state shear pulverization to form materials that can be processed as thermoplastics at crosslinked rubber concentrations of from 10 to as high as 95 wt. %, based on the total solids of the material. The method may further comprise kneading the pulverized product to form useful articles, such as roofing membranes and shoe soles.
