Abstract

PURPOSE: To prepare a colorless polyester resin having a reduced carboxyl group number, efficiently in a short time, by reacting a polyester with a monofunctional epoxy compound in the presence of an alkaline earth metal compound and phosphoric acid or its ester.
CONSTITUTION: A mixture comprising (A) a polyester consisting of ≥80 mole % of ethylene terephthalate unit in the recurring unit, (B) a monofunctional epoxy compound (0.1W10 wt% on the basis of (A)), e.g. phenyl glycidyl ether, etc., (C) an alkali earth metal compound, e.g. calcium acetate, etc., and (D) phosphoric acid or its ester (0.05W3.0 equivalent on the basis of (C)), is reacted to give the desired polyester.
EFFECT: Hydrolysis resistance is remarkably improved; and the polyester is particularly useful for industrial products, e.g. tire cord, fishing net, etc.
