    • PURPOSE: To provide the titled composition having excellent stability against heat and oxidation, and suitable for various molded articles, by compounding a polyolefin resin with a specific phenolic compound and a sulfur compound.
      CONSTITUTION: The objective composition is prepared by compounding 100pts.wt. of a polyolefin resin (especially polypropylene) with 0.05W1pt.wt. of a mixture of 2,2'-2"-tris[3-(3-methyl-5-butyl-4-hydroxyphenyl)-propionyloxy]ethyl isocyanurate and pentaerythritol-tetrakis(β-alkylthiopropionate) of formula (R is 4W 20C alkyl) [e.g. pentaerythritoltetrakis(β-dodecylthiopropionate)] at a weight ratio of 1:(0.5W15), especially 1:(2W6). The light resistance of the composition can be improved by the addition of a light-stabilizer, a hindered amine stabilizer, etc.
