Abstract
PURPOSE: After a specified hydroxyethyl isophthalate is added as a modifier to oligomers prepared by the direct polycondensation method to form a uniformly melted liquid, a pigment of titanium oxide is added, then the polycondensation reaction is effected to produce a modified polyester dyeable with basic dyes.
CONSTITUTION: A modifier such as sodium 3,5-di(carbo-2-hydroxyethyl ester) benzene-sulfonate, which is prepared from a dialkyl ester of isophthalic acid bearing a sulfonate salt group and has 40W74% ester interchange rate, as a modifier in an amount of 0.5W10mol% is combined with more than 90mol% of direct-polycondensation oligomers of ethylene terephthalate of 2W9 average polymerization degree, which is determined by the measurement of saponification and acid values. They are kept at 270W260°C for 1W60min to give a uniform melted liquid and titanium oxide is added, preferably by 0.01W5wt%, then the polymerization is completed to produce the objective modified polyester.
