Abstract
Abstract The present invention relates to an electrolessly metal plated plastic substrate consisting of (a) a terpolymer made from 65 to 90% styrene, 5-35% acrylonitrile and 0.25 to 25% vinylpyridine monomers; (b) graft polymers made from 7 to 80% styrene, 3 to 34% acrylonitrile, 0.25 to 25% vinylpyridine monomers or 10 to 90% elastomeric spines selected from the group consisting of (i) polybutadiene, (ii) butadiene-styrene copolymers and (iii) ethylene-propylene-dicyclopentadiene terpolymers; (c) a blend of the terpolymers defined in (a) above in admixture with not more than 45% of a resinous ABS polymer or (d) a blend of the graft polymer defined in (b) above in admixture with not more than 45% of a resinous ABS polymer, all of said percentages being by weight.
