Abstract

PURPOSE: The titled composition exhibiting improved heat distortion resistance even in case of containing a large amount of an electrically-conductive material and a processing auxiliary, having high productivity, obtained by using polyvinyl chloride and a copolymer consisting of vinyl chloride and a copolymer comprising α-methylstyrene.
CONSTITUTION: (A) Polyvinyl chloride and/or a copolymer consisting essentially of vinyl chloride and blended with (B) a polymer or copolymer comprising α- methylstyene as one component, (C) a processing auxiliary, and (D) an electrically-conductive material. The copolymer consisitng essentially of vinyl chloride comprises an α-olefin such as ethylene, propylene, etc. and vinyl chloride, and preferably consists of 60W97wt% comonomer component and 40W3wt% vinyl chloride component. The component B preferably comprises ≥30wt% α-methylstyene and also butadiene, acrylonitrile, etc.
