A molding resin composition comprising (A) a saturated polyester resin, (B) a graft copolymer and (C) a rubber-reinforced resin, wherein a weight ratio of the saturated polyester resin (A) to a total weight of the graft copolymer (B) and the rubber-reinforced resin (C) is from 95:5 to 5:95, a weight ratio of the graft copolymer (B) to the rubber-reinforced resin is from 100:0 to 5:95, and the graft copolymer (B) is one prepared by copolymerizing an unsaturated epoxide monomer and at least one monomer selected from the group consisting of aromatic vinyl monomers, cyanated vinyl monomers and alkyl unsaturated carboxylates in the presence of an ethylene-α-olefin base rubber, which can provide a molded article having improved impact strength, weld strength, stiffness and mold shrinkage factor.
一种成型树脂组合物,包括(A)饱和聚酯树脂,(B)接枝共聚物和(C)橡胶增强树脂,其中饱和聚酯树脂(A)与接枝共聚物(B)和橡胶增强树脂(C)总重量的重量比为95∶5至5∶95,接枝共聚物(B)与橡胶增强树脂的重量比为100∶0至5:接枝共聚物 (B) 是在乙烯-α-烯烃基橡胶存在下,通过共聚不饱和环氧单体和至少一种选自芳香族乙烯基单体、氰化乙烯基单体和烷基不饱和羧酸酯的单体而制备的,可提供具有更高的冲击强度、焊接强度、刚度和模具收缩因子的成型制品。
