ABSTRACT:
A vinyl chloride resin composition for production of hard articles. The composition comprises 100 parts by weight of a graft polymer and not more than 40 parts by weight of electrically conductive carbon black. The graft polymer is obtained by polymerizing 99 to 60% by weight of vinyl chloride or a monomeric mixture composed of at least 80% by weight of vinyl chloride and not more than 20% by weight of a monomer copolymerizable with it in the presence of 1 to 40% by weight of a copolymer composed of 5 to 75% by weight of methyl methacrylate and 95 to 25% by weight of ethylene.
