ABSTRACT:
An electroconductive resin composition is a blend of 5-30% by weight of carbon black and a graft-polymer. The graft-polymer is obtained by graft-polymerizing 99-76 parts by weight of monomeric vinyl chloride to 1-15 parts by weight of an ethylene-vinyl acetate copolymer, the ethylene-vinyl acetate copolymer containing 10-65% by weight of vinyl acetate. The electroconductive resin composition has superior heat resistance and mechanical strength and improved flowability and heat stability. The electroconductive resin composition is particularly suitable for preparing videodisc records.
