Abstract

PURPOSE: To prepare an aromatic polyester having high intrinsic viscosity, at low temp. in a short time, using only a small amount of catalyst, by the reaction of an aromatic diester with an aromatic dicarboxylic acid in the presence of a metal naphthenate.
CONSTITUTION: An aromatic polyester is prepared by reacting (A) at least one aromatic diester of formula I (R is H, 1-6C alkyl, ≤ 8C cycloalkyl; Ar1 is arylene), such as diester of formic acid, lactic acid, etc., with (B) at least one aromatic dicarboxylic acid of formula II (Ar2 is arylene), such as terephthalic acid, isophthalic acid, 2,6-naphthalene dicarboxylic acid, etc., in the presence of (C) a metal salt of naphthenic acid.
