PURPOSE:The titled composition having small warpage, and improved water resistance, heat resistanceand impact resistance, obtained by blending a thermoplastic polyester with a specific modified propylene polymer and/or modified 4-methyl-1-pentene polymer. CONSTITUTION:(A) 70-99pts.wt., preferably 80-99pts.wt. thermoplastic polyester is blended with 0.5-30pts.wt., preferably 1-20pts.wt. (B) modified propylene polymer having 0.05-5.0wt%, preferably 0.5-3.0wt% grafted amount of component unit of unsaturated carboxylic acid or its derivative, and (D) 10-20pts.wt. inorganic fiber (based on 100pts.wt. components A+B and/or component C). Polyethylene terephthalate is preferable as the component A. Maleic acid or nadic acid is preferable as the unsaturated carboxylic acid of the components B and C. |
