PURPOSE:To obtain the title composition improved in tensile strength and impact resistance without impairing heat resistance and stiffness, etc., by blending a crystalline polyolefin with an inorganic filler, specific cyclic phosphorus compound, aliphatic monocarboxylic acid copper salt, etc., at specific amounts. CONSTITUTION:The aimed polyolefin composition obtained by blending 100 pts. wt. composition obtained by blending a crystalline polyolefin with an inorganic filler (e.g. talc or mica) with (A) 0.05-1 pts.wt. cyclic phosphorus compound expressed by formula I (Ar1 and Ar2 are arylene, etc.) and (B) 0.05-1 pts.wt. copper aliphatic monocarboxylate or (D) 0.001-1 pts.wt. fluoro-phosphite expressed by formula II (R is 1-4C alkylidene, etc.; Ar3 and Ar4 are alkylarylene; n is 0 or 1). |
