TITLE: WEATHER-RESISTING EXTRUDED RUBBERY ARTICLES HAVING ON THE SURFACE THEREOF A THIN LAYER OF A COLORED RUBBERY MATERIAL ABSTRACT OF THE DISCLOSURE A weather-resisting extruded rubbery article based on carbon black-incorporated EPDM rubber substrate having on the surface thereof a thin layer of a colored rubbery material of a smooth or suède-like appearance integrally formed on the substrate, characterized in that the colored rubbery material has been derived from 75-0% by weight of EPDM and 25-100% by weight of a graft copolymer of EPDM and vinyl chloride together with one or more coloring fillers. The weather-resisting extruded rubbery article is manufactured by subjecting the carbon black-incorporated EPDM and a colored rubbery compound comprised of EPDM and a graft copolymer of EPDM and vinyl chloride, one or more coloring fillers, a vulcanizing system and, if necessary, a foaming agent to extru- sion molding followed by vulcanization with or without simultaneous foaming and, if necessary, the extruded rubbery article thus obtained which has on the surface thereof a thin layer of a colored and foamed rubbery material integrally formed on the substrate is polished with an abrasive to remove the skin of the colored and foamed rubbery material thereby providing the surface of a suède- like appearance, characterized in that the colored rubbery compound contains 75-0% by weight of EPDM and 25-100% by weight of the graft copolymer of EPDM and vinyl chloride. The weather-resisting extruded rubbery articles are useful as parts of motor vehicles exposed under severe conditions and as indoor and outdoor ornaments and buffer materials. - 1 -
