Abstract

PURPOSE: To obtain the titled molded article having a sufficiently low content of terminal carboxyl groups without reducing the polymerization degree, by melt molding a saturated polyester in the presence of a specific epoxy compound.
CONSTITUTION: In melt molding a saturated polyester, preferably 0.3W1.5pts.wt., based on 100pts.wt. polyester, epoxy compound expressed by the formula, e.g. N- glycidylcyclohexenedicarboximide, is incorporated with the polyester. Preferably, 0.005W0.15wt%, based on the total acidic component constituting the polyester, alkali metallic halide, e.g. potassium iodide, is mixed to further enhance the effect on the reduction in the content of terminal carboxyl groups in the saturated polyester.
