Abstract: Since their surfaces are inactive, polyolefin resins are difficult to plate. A plating method utilizing sensitizing-activation of the surface has been used for plating polyolefin resins. Many attempts have been made to improve the plating properties of the surfaces of polyolefin resins, for example, a mechanical method, a method employing a solvent, a method of coating other types of resins on the surface, etc. As methods modifying the plastics themselves, there are several; a method of introducing polar radicals by graft polymerization, etc., a method of introducing atactic polypropylene or block copolymer of polypropylene and polyethylene, a method of mixing rubber or a copolymer of ethylene and vinyl acetate, a method of mixing in an inorganic filler, etc.
