POLYPROPYLENE TALC COMPOSITES - INTERFACIAL MODIFICATIONS INDUCED BY CHEMICALLY-MODIFIED ATACTIC POLYETHYLENE FROM INDUSTRIAL-WASTES, TENSILE BEHAVIOR/

The tensile behaviour of polypropylene-based composite materials, as a thermoplastic matrix, and talc particles, as a mineral reinforcement, is discussed on the basis of the interfacial changes that are caused by using a chemically modified atactic polymer (originating from an in dustrial waste) as an interfacial agent on the side of the matrix in t he composites. Enhancement of their mechanical properties can be concl uded.
