PURPOSE:To improve the heat stability of the title vinyl chloride resin composition, by mixing a vinyl chloride resin with an antimony mercaptide compound and an aluminosilicate having a zeolitic crystal structure. CONSTITUTION:A vinyl chloride resin (A) is mixed with an antimony mercaptide compound (B) and an aluminosilicate (C) having a zeolitic crystal structure to obtain the purpose vinyl chloride resin composition. Examples of component B include compounds of formulas I, II and III, and its amount is suitably about 0.01-10pts.wt. per 100pts.wt. component A. Examples of component C which is desirable include zeolite A and its amount is suitably about 0.01-10ptw.wt. per 100pts.wt. component A. It is possible to add an organic acid metal salt (e.g., sodium stearate), an organic phosphite compound (e.g., triphenyl phosphite), etc., in addition to components B and C.
