PROBLEM TO BE SOLVED: To obtain a vinyl chloride resin composition which has a coefficient of linear expansion lower than that of a conventional product and excellent impact resistance, and to provide a molded article thereof. SOLUTION: The vinyl chloride-based graft copolymer composition contains a vinyl chloride-based graft copolymer obtained by graft copolymerizing 70-99 wt.% of a vinyl monomer mainly composed of vinyl chloride with 1-30 wt.% of an elastomer component (a) having an average particle diameter less than 0.15μm, an impact improver (b) having an average particle diameter of 0.2μm or more and an acicular or platelike inorganic material. Weight ratios of these components are as follows: the vinyl chloride-based graft copolymer/the inorganic material = 100/10-100/60 and the components (a)/(b) = 30/70-95/5. COPYRIGHT: (C)2003,JPO
