Abstract
PURPOSE: To obtain the titled composition dyeable with a basic dye with good particle dispersibility, slipperiness and light screening properties, by the addition of a fine particle together with ethylene glycol to a reaction system before the completion of polycondensation of metal sulfonate group-contg. butylene terephthalate.
CONSTITUTION: Terephthalic acid or a deriv. thereof (A) metal sulfonate group- contg. isophthalic acid (B) and an ester (C) obtd. by the esterification or ester interchange of 1,4-butanediol, or an oligomer thereof are subjected to polycondensation under reduced pressure. Before the completion of the polycondensation, fine particles such as titanium oxide of average particle size 0.01W5.0μ classified in ethylene glycol, or ethylene glycol are added to the reaction system, and the polycondensation is completed to obtain a composition consisting of a copolyester contg. 0.3W4.0mol% component B and having repeating units of which 70mol% or more is composed of butylene terephthalate and 0.01W10mol% of ethylene terephthalat, and 0.01W5wt%, based on the polymer, fine particles.
