PURPOSE:To obtain the subject composition having excellent heat-resistance. chemical resistance impact resistance, Geer oven life, resistance to anti-freeze. moldability, etc., by using a polyamide resin, a polyolefin. etc., glass fiber and an additive composed of specific compounds as essential components. CONSTITUTION:The objective composition contains (in terms of resin component) (A) 30-90wt.% of a polyamide resin, (B) 70-10wt.% of a polyolefin and a polyolefin modified with an unsaturated carboxylic acid (the sum of A and B is 100 pts.wt.), (C) 5-50pts.wt. of glass fibers and (D) an additive composed of (i) 0.1-2 pts.wt. of N,N'-bis[3-(3,5-di-t-butyl-4-hydroxyphenyl) propionyl]hydrazine, (ii) 0.05-5 pts.wt. of pentaerythritoltetrakis[3-(3,5-di-t-butyl-4- hydroxyphenyl propionate] (iii) 0.05-0.5 pts.wt. of distearyl pentaerythritol diphosphite and (iv) 0.15-1 pt.wt. of distearyl 3,3'-thiodipropionate. |
