  • Electroconductive resin composition and a videodisc record
    Patent number: 4465615
    Abstract: An electroconductive resin composition is a blend of 5-30% by weight 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 ethylenevinyl acetate copolymer, the ethylenevinyl 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 video disc records.
    Type: Grant
    Filed: April 26, 1983
    Date of Patent: August 14, 1984
    Assignee: Tokuyama Sekisui Kogyo Kabushiki Kaisha
    Inventors: Akio Hata, Hiroshi Kake, Noriki Fujii
