Abstract
Abstract There is here provided a thermoplastic resin composition which comprises (I) 99 to 1% by weight of an aromatic polyester resin, (II) 1 to 99% by weight of at least one kind of resin selected from the group consisting of a polyphenylene ether resin, a mixture of the polyphenylene ether resin and a styrene polymer, a polycarbonate resin, and a polyarylene sulfide resin, (III) 0.1 to 100 parts by weight, based on 100 parts by weight of the aforesaid resins (I)+(II), of a multi-phase structure thermoplastic resin which is composed of 5 to 95% by weight of an epoxy group-containing olefin copolymer and 95 to 5% by weight of a vinyl polymer or copolymer obtained from at least one kind of vinyl monomer, either of both the components being formed with a dispersion phase having a particle diameter of 0.001 to 10 mu m. A method for preparing the above-mentioned thermoplastic resin composition is also provided here.
