PURPOSE:To obtain efficiently the title homogeneous composition excellent in mechanical properties and inorganic salt resistance, by mixing a mixture of a polyamide resin, PP and an ethylene/alpha-olefin copolymer with a specified amount of a mixture of an alpha,beta-unsaturated carboxylic acid (derivative) and an organic peroxide and melt-kneading the resulting mixture. CONSTITUTION:100pts.wt. mixture of 94-50wt.% polyamide resin (A) of a relative viscosity of 1.5-5.0 (as measured in a 1% sulfuric acid solution at 25 deg.C), 5-45wt.% PP (B) of an MFI of 0.1-50g/10min and 1-20wt.% ethylene/alpha- olefin copolymer (C) of an MFI of 0.5-100g/10min and an ethylene content of 95-30wt.% is mixed with 0.01-10pts.wt. alpha,beta-unsaturated carboxylic acid (derivative) (D) such as maleic anhydride, N-phenylamaleimide or glycidyl (meth) acrylate and 0.001-2pts.wt. organic peroxide (E) such as dicumyl peroxide, and the resulting mixture is melt-kneaded with, e.g., a Henschel mixer. |
