If the average degree of polymerization of the vinyl chloride resin as a raw material of the chlorinated vinyl chloride resin is less than 600, sufficient mechanical strength cannot be obtained, while if the degree of polymerization exceeds 1500, It is not preferable because processing is not easy. When the chlorination degree of the chlorinated vinyl chloride resin is less than 62% by weight, a composition having sufficient heat resistance cannot be obtained. On the other hand, when the chlorination degree exceeds 70% by weight, the melt viscosity increases. However, it is not preferable because processing of the resin composition involves technical difficulties. In the present invention, the “vinyl chloride resin” is a homopolymer of vinyl chloride and a monomer copolymerizable with vinyl chloride (eg, ethylene, propylene, vinyl acetate, allyl chloride, allyl glycidyl ether, acrylic acid). Esters, vinyl ethers and the like). The composition of the present invention is characterized by adding a hydroxypolycarboxylate to a chlorinated vinyl chloride resin. By adding such a hydroxypolycarboxylate, the thermal stability of the composition is significantly improved.
