PURPOSE:The title composition excellent in stabilizinag effect and mechanical strength and free of coloring, prepared by mixing a halogen-containg resin with an aluminosilicate having a zeolitic crystal structure and a specified dihydropyridine compound. CONSTITUTION:100pts.wt. halogen-containing resing (e.g., PVC) is mixed with 0.01-10pts.wt. aluminosilicate having a special three-dimensional zeolitic crystal structure (e.g., zeolite A, X, Y or P), 0.01-1.5pts.wt. dihydropyridine compound of the formula (wherein R is alkyl, alkenyl or aryl) and, optionally, 0.01-5pts.wt. metal salt of an organic acid (e.g., calcium stearate), a metal inorganic salt (e.g., ZnO) and an organophosphite compound and/or 0.01-10pts.wt. epoxy compound, a phthalate ester plasticizer, an antioxidant, an ultraviolet absorber, etc.
