Abstract
Abstract This invention is addressed to the electroplating of plastic compositions containing isotactic polypropylene wherein articles formed of a polymeric composition selected from the group consisting of a mixture of from 75 to 97% by weight isotactic polypropylene and 3 to 25% of an olefin copolymer having low crystallinity and a graft copolymer formed of 75 to 97% by weight of isotactic polypropylene onto which is grafted 3 to 25% by weight of a copolymer of ethylene and propylene containing more than 10% by weight ethylene are electroplated to form a thin coat of a metal on at least one surface thereof.
