Abstract
The present invention provides a method of improving the wear resistance of a polymeric composite comprising a polyamide and a polypropylene. The polymeric composite is a component of a tribological wear system in which a surface of the polymeric composite bears against another surface causing friction and wear of the polymeric composite. By the present method, at least one crystalline polymer is functionalized to graft with at least one of the polyamide and the polypropylene to form the composite.
