ABSTRACT OF THE DISCLOSURE A moldable resin composition is discloses, which has a 200°C heat stability of 60 minutes of more and which comprises a polymer, calcium carbonate and a heat stabilizer, the polymer being produced by polymerizing (i) monomeric vinyl chloride or (ii) a monomer mixture composed of (a) monomeric vinyl chloride and (b) a monomer which is copolymerizable therewith and which yields a homopolymer having a glass transition temperature below 30°C, in the presence of 10 to 200 parts by weight, per 100 parats by weight of said monomeric vinyl chloride (i) or said monomer mixture (ii), of a themoplastic polyurethane elastomer which is soluble in monomeric vinyl chloride at the polymerization condition and has a softening point in the range of from 20 to 100°C. The resin composition can provide a molded articles containing very few fisheyes and having a smooth surface.
