PURPOSE:To obtain a polyolefinic resin composition, excellent in feeling with hand, touch feeling and rigidity and stable to oxidative deterioration by light and heat. CONSTITUTION:A polyolefinic resin composition is obtained by blending 100 pts.wt. total amount of (A) 50-95 pts.wt. polyolefinic synthetic resin, (B) 5-50 pts.wt. powdery filler (e.g. calcium carbonate) and (C) 0-5 pts.wt. pigment (e.g. carbon black) with (D) 3,9-bis[2-{3-(3-t-butyl-4-hydroxy-5-methylphenyl) propionyloxy}-1, 1-dimethylethyl]-2,4,8,10-tetraoxaspiro[5,5] undecane, (E) a sulfur-based compound expressed by formula I (R<1> is 2-18C alkyl), (F) a phosphorousbased compound expressed by formula II (one of R<2> to R<4> is butyl and the remaining two are H, etc.), (G) a benzoate-based compound expressed by formula III (R5 and R6 are t-butyl, etc.), (H) a low-molecular weight hindered piperidine-based compound selected from formula IV, etc., and (I) a hindered piperidine-based compound, selected from formula V, etc., and having >=500 molecular weight. |
