Abstract

PURPOSE: To prepare a modified polyester easily which is uniformly dyeable with basic dyes, by adding 2-hydroxyethyl isophthalate having a sulfonic acid salt group, and an aromatic arboxylate to the oligomer prepared by the direct polymerization method, and polymerizing the mixture.
CONSTITUTION: Preferably 0.5W10 mol % of 2-hydroxyethyl isopthalate having a sulfonic acid salt and a lower alkyl ester of an aromatic carboxylic acid I or II (R and R' are 1W4C alkyl), e.g. methyl benzoate, etc. (20W50 % on the basis of the isophthalate) are added to the oligomer prepared by the direct polymerization of terephthalic acid and the mixture is polymerized to give a modified polyester.
