PROBLEM TO BE SOLVED: To obtain a polyolefin resin composition suitable for hightemperature processing, excellent in heat resistance and resistance to (pink)-discoloration, thus useful for film molded products by incorporating a polyolefin resin hating specific physical properties with a phenolic antioxidant and a specific compound. SOLUTION: This resin composition is obtained by incorporating (A) 100 pts.wt. of a polyolefin resin 0.1-50g/10min in MFR (at 190 deg.C under a load of 2.16 kg) with (B) pref. 0.01-0.50 pts.wt. of a phenolic antioxidant, (C) pref. 0.01-0.50 pts.wt. of bis(2,6-di-t-butyl-4-methylphenyl)pentaerytritol-di-hosphite, and pref. (D) pref. 0.01-5.0 pts.wt. of a metallic soap (pref. a fatty acid metal (either Li, Mg, Ca or Zn) salt, esp. pref. zinc stearate). The component C is capable of suppressing/preventing the molded products of this composition from yellowing, browning or pink-discoloration supposed to be attributable to the component B. |
