PURPOSE:A resin composition that is made by adding an epoxy compound and an organic sulfonate salt to a thermoplastic polyester, thus showing high shape stability in the molten state and having high heat stability and mechanical properties. CONSTITUTION:To 100pts.wt. of a thermoplastic polyester, preferably polybutylene terephthalate, are added (A) 0.1-40, preferably 1-30 parts, of an epoxy compound bearing at least one of epoxy groups in the molecule, preferably a bisphenol- A type epoxy compound of formula I (n is 0-10) and (B) 0.001-10, preferably 0.005- 3 parts, of at least one selected from organic sulfonate salts of formula II (M is Li, Na, etc.; R', R'' are methyl, ethyl, etc.) and sulfate salts of formula: R(SO3M)n (M is a metal; R is an organic radical; n is 1 or more) and they are kneaded under molten. |
