Abstract
PURPOSE: To obtain a polyester having excellent hydrolysis resistance, by reacting an epoxy compound with a polyester consisting of an aromatic dicarboxylic acid and an organic dihydroxy compound or of a hydroxy aromatic monocarboxylic acid.
CONSTITUTION: A polyester, ≥0.3 intrinsic viscosity which is one consisting of aromatic dicarboxylic acid component (A) and an organic dihydroxy compound component (B) one consisting of a hydroxy aromatic monocarboxylic acid component (C) or one consisting of components A, B and C, is reacted in the molten state with an epoxy compound of the formula, wherein R1 and R2 are each an esterifiable functional group-free saturated aliphatic, alicyclic or aromatic group and R3 is H or a saturated aliphatic group. The amount of the epoxy compound used is 0.05W5mol% based on total acid component constituting the polyester, and excessive use is not preferred because of discoloration and reduction in the degree of polymerization.
