PURPOSE:To obtain a resin compsn. having excellent moldability and impact resistance, by blending a wholly arom. polyester resin composed of three specified arom. repeating components as principal structural units with a polyether oil. CONSTITUTION:A resin compsn. consists of a wholly arom. polyester resin composed of repeating components of formulas I, II (wherein n is 0 or 1) and III as principal structural units and a polyether oil. The polyether oil is a material having such a basic structure that benzene nuclei are bonded to one another through at least either of ether and thioether linkages. For example, polyphenyl ether oil including structural isomers composed of benzene nuclei and ether linkages is commercially available. The polyether oil is used in an amount of pref. 3.0-0.05wt%. |
