PURPOSE:The titled composition having extremely improved smell while keeping heat aging characteristics, obtained by blending a crystalline propylene polymer with a specific amount of specified stabilizers and an inorganic substance. CONSTITUTION:(A) 100pts.wt. crystalline propylene polymer having preferably 1-100g/10min MFR is blended with (B) 0.01-1pt.wt. hindered phenolic stabilizer selected from tetrakis[methylene-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate] methane and 1,3,5-tris-(4-t-butyl-3-t-hydroxy-2,6-dimethylbenzyl)isocyanuric acid, (C) 0.01-1pt.wt. thioether stabilizer selected from distearyl thiodipropionate and pentaerythritol tetra (beta-laurylthiopropionic ester), and (D) 0.01-1pt.wt. inorganic substance selected from hydrotalcite and magnesium oxide. |
