Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
In an electrically conductive resin composition, suitable for electroplating, comprising (a) 100 parts by weight of a polyolefin resin selected from the group consisting of homopolymers of ethylene, homopolymers of propylene, copolymers of ethylene and propylene, copolymers of ethylene with other alphaolefins, copolymers of propylene with other alpha-olefins, and mixtures thereof, (b) 0.1-10 parts by weight of sulfur, (c) 0.05-10 parts by weight of a plate adhesion promoter and (d) 10-70 parts by weight of an electrically conductive carbon black, the improvement which comprises adding to said composition a flow improver in an amount of 4-40 parts by weight per 100 parts by weight of (a) plus (d), said flow improver being selected from the group consisting of a softening agent derived from petroleum, a polyalkylene glycol and mixtures thereof, said softening agent being derived from petroleum which consists of naphthenic process oil, aromatic process oil, paraffinic process oil or liquid paraffin, said polyalkylene glycol having alkylene radicals of 1 to 4 carbon atoms.
