Abstract

PURPOSE:To obtain the title composition which can give a molding excellent in transparency, and discoloration resistance and retentivity of mechanical properties after irradiation, by mixing a propylene polymer with a specified hindered amine compound, a phosphorus-containing antioxidant and a dibenzylidenesorbitol compound. CONSTITUTION:The title composition is prepared by mixing 100pts.wt. propylene polymer with a triazine ring-containing hindered amine compound (A) {e.g., poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2, 4-diyl][(2,2,6,6,-tetrame thyl-4-piperidyl)imino]hexamethylene[(2,2,6,6-tetramethyl-4-piperidyl) imino]]}, a phosphorus-containing antioxidant (B) [e.g., bis(2,4-di-t-butylphenyl) pentaerythritol diphosphite] and a dibenzylidenesorbitol compound (C) (e.g., 1.3,2.4-dibenzylidenesorbitol), each in an amount of 0.01-1pt.wt.
