PURPOSE:To provide the titled compsn. which has excellent compatibility, mechanical properties and surface gloss and is lowly water-absorptive and suitable for use in the production of automobile parts, appliance parts, etc., consisting of a specified modified polyolefin, a polyamide and a polyolefin. CONSTITUTION:100pts. (by weight; the same applies hereinbelow) mixture of 10-95wt% polyolefin (a) (e.g., a polymer mainly composed of propylene such as PP) and 90-5wt% polyamide (b) (e.g., nylon 6) is blended with 0.001-10pts. unsaturated carboxylic acid (derivative) (c) [e.g., maleic acid (anhydride)] and optionally, 0.001-5pts. org. peroxide (d). The mixture is melt-kneaded at 180-300 deg.C to carry out a grafting reaction, thus obtaining a modified polyolefin (A). 5-95pts. component A is blended with 5-95pts. polyamide (B) and 0-90pts. polyolefin (C) in such a proportion that the combined amount of the components A, B and C is 100pts. and the combined amount of the polyolefins in the compsn. is 10-90wt%. The mixture is melt-kneaded.
