PURPOSE: The titled composition which can give a molding excellent in mechanical strength, transparency, smoothness, gloss, etc., prepared by kneading a polyolefin resin modified with an unsaturated carboxylic acid (derivative) or a mixture of this resin with an unmodified polyolefin resin with a cellulosic material. n CONSTITUTION: 5W95wt% modified polyolefin resin of a content of an unsaturated carboxylic acid (derivative) added of 0.1W14wt%, obtained by mixing with heating a polyolefin resin with an unsaturated carboxylic acid (derivative), eg., maleic acid (anhydride) or maleamide, and a radical generator in the presence (or absence) of a solvent or mixture (A) of this resin with an unmodified polyolefin resin is kneaded with 95W5wt% cellulosic material (B) such as a lignocellulose fiber containing a chemically modified cellulose obtained by esterifying, etherifying, carboxylating or halogenating a cellulosic material containing cellulose and, optionally, 2W40pts.wt., per 100pts.wt. total of components A and B, plasticizer (C) such as dioctyl phthalate at 140W200°C for 10W30min. n COPYRIGHT: (C)1987,JPO&Japio |
