PURPOSE:The titled composition providing injection-molded articles having improved appearance, showing improved fluidity, fiber dispersibility and mold releasability free from problem of smell, comprising a polyolefin, vegetable fiber of fibrillated cellulose and a specific amount of polyolefin wax. CONSTITUTION:The aimed composition comprising (A) a polyolefin (preferably polymer consisting essentially of propylene), (B) vegetable fiber consisting essentially of fibrillated cellulose (e.g. fiber obtained by opening and fibrillating old newspaper, waste paper, etc.) and (C) 0.5-20pts.wt., preferably 3-10pts.wt. based on 100pts.wt. total amounts of the components A+B of polyolefin wax (preferably PE wax or PP wax having 1,000-6,000 number-average molecular weight). The amount of the component B blended is preferably 10-60pts.wt. based on total amounts of the components A+B. |
