Abstract

PURPOSE: To provide the titled compsn. in which discoloration resistance, light resistance and heat resistance are improved, containing dipentaerythritol diphosphite and at least one member selected from a phenolic antioxidant or a thioether antioxidant, an ultraviolet absorber and a light stabilizer.
CONSTITUTION: 0.01W5wt% dipentaerythritol diphosphite and at least one member selected from a phenolic antioxidant (e.g. 2,6-di-tert.-butyl-4-methylphenol), a thioether antioxidant (e.g. dilauryl thiodipropionate), an ultraviolet absorber and a light stabilizer [e.g. 2-(2-hydroxy-5-methyphenyl)-benzotriazole], are blended with a polyolefin resin such as polyethylene or polypropylene to obtain the desired resin compsn. Dipentaerythritol diphosphite can be synthesized by the ester exchange reaction between triphenyl phosphite and dipentaerythritol.
