Abstract
PURPOSE: In the production of polyester, 2-hydroxyethyl ester and lower dialkyl ester of isophthalic acid bearing sulfonate groups are added as modifiers to produce high-quality polyester readily dyeable with cationic dyes.
CONSTITUTION: In the production of modified polyesters containing more than 80 mole% of ethylene terephthalate and 0.5W10 mole% of ethylene isophthalate bearing sulfonate groups as structural units using oligomers from the direct polycondensation of terephthalic acid, 2-hydroxyethyl ester of isophthalic acid bearing sulfonate groups and lower dialkyl ester of isophthalic acid bearing sulfonate groups in 20W90 mole% based on the hydroxyethyl isophthalate are added as modifiers. The dialkyl isophthalate used is, e.g., sodium 3,5-di(carbomethoxy)benzenesulfonate.
