PURPOSE:To provide the titled compsn. having excellent coatability, flow characteristics and resistance to impact, marring, oils and heat, by heating, melting and kneading a resin mixture in the presence of a metal oxide, etc., and uniformly blending it with a polyolefin. CONSTITUTION:A resin mixture of 100pts. (by weight; the same applies hereinbelow) of the combined quantity of 10-90pts. PP (A) having an MFR of 0.3-60g/10min and 90-10pts. halogenated butyl rubber (B) having a Moony viscosity of 25-100 (100 deg.C), 10-120pts. olefin rubber (C) having a Moony viscosity of 25-100 (100 deg.C), an iodine value of 30 or below and an ethylene content of 35-85wt%, 5-120pts. mineral oil softener (D), 1-90pts. modified polyolefin (E) obtd. by adding an unsaturated carboxylic acid (derivative) to a polyolefin and 2-100pts. nitrile rubber (F) is heated, molten and kneaded in the presence of 0.2-10wt% (based on the quantity of the mixture) metal oxide (e.g., ZnO) and/or metal chloride (e.g., ZnCl2) at 160-250 deg.C for 1-10min and uniformly blended with a polyolefin. |
