Abstract: PURPOSE:To improve the rigidity, impact resistance, moldability and appearance of a molding without detriment to balance among them, by mixing a thermoplastic polyester with modified polyphenylene sulfide and a glycidyl group- containing olefin copolymer. CONSTITUTION:A resin composition formed by mixing 100pts.wt. thermoplastic polyester (A) with 1-100pts.wt. polyphenylene sulfide (B) modified by treatment with acid and/or hot water (>=80 deg.C) and 0.5-80pts.wt. glycidyl group-containing olefin copolymer. When the degree of polymerization of the thermoplastic polyester used is excessively high, a molding of good surface gloss can not be obtained, white when it is excessively low, sufficient mechanical properties can not be attained. This composition is usually preferred to have an intrinsic viscosity of 0.5-1.3 (as measured in a 0.5% o-chlorophenol solution at 25 deg.C).

Abstract: PURPOSE:To obtain the titled high polymerization degree formed article outstanding in heat and solvent resistances and mechanical strength, by using an aromatic copolyester of specified viscosity constituted by isophthalic acid, terephthalic acid and bisphenol S units. CONSTITUTION:The objective formed article can be obtained by using an aromatic copolyester constituted by structural units of formulae I, II and III, respectively, with the molar ratio of the units III/II of 1/9-6/4, having a logarithmic viscosity >=0.55 determined in the form of an orthochlorophenol solution of a concentration 0.5g/dl at 25 deg.C. Sad aromatic copolyester can be prepared, for example, by the following process: first, isophthaloyl dichloride and terephthaloyl dichloride are dissolved in a solvent prepared by distillation and purification, in the presence of 0.1-10wt% of isophthaloyl dichloride and/or terephthaloyl dichloride, of methylene dichloride. Following that, the resultant organic solvent solution and an aqueous NaOH solution of bisphenol S treated at 60-80 deg.C for 0.1-5hr are brought to interfacial polycondensation using as a catalyst a phosphonium salt.
