PURPOSE:To obtain an insert molded piece wherein high and low temperature impact properties are improved, by using for insert molding a composition in which thermoplastic polyester resin as a main component, an olefin copolymer and a graft copolymer with a polymer having a structure as shown in the specified general formula and others are mixed. CONSTITUTION:To a thermoplastic polyester resin of 100 pts.wt., an olefin copolymer consisting of alpha-olefin and glycidyl ester of alpha,beta-unsaturated acid and a graft copolymer of 0.5-80 pts.wt. in which one kind or two or more kinds of polymer or copolymer constituted mainly of repeat unit to be shown in the formula are bonded chemically in a branching or cross-linking way are added. A resin composition in which a fibrous filler, a non-fibrous inorganic filler or an admixture of them of 5-200 pts.wt. are mixed and a metal or an inorganic solid body are molded by insert molding so as to obtain an insert molded piece. |
