Abstract
PURPOSE: To obtain polyester with reduced terminal carboxyl groups having excellent hydrolysis stability by reacting a specific epoxy compound in a moleten state with polyester comprising an aromatic dicarboxylic acid component and an organic dihydroxy compound component or the like.
CONSTITUTION: The polyester constituted from an aromatic dicarboxylic acid (A) and an organic dihydroxy compound component (B), or a hydroxy aromatic monocarboxylic acid component (C) or from (A), and (B), (C) components of which intrinsic viscosity is above 0.3 is reacted in a molten state with an epoxy compound of the formula (wherein R1 and R2 are H, aliphatic group without ester-forming functional group or may be mutually bound. R3 is n-valent organic residue without ester-forming functional group, n is 1, 2) to produce polyester with reduced terminal carboxyl groups.
