Abstract

PURPOSE:To prepare a polyester causing either clogging nor filament breakage, by polycondensing an arom. dicarboxylic acid or the like with a glycol in the presence of an Sb compd. as a polycondensation catalyst with specific inactive inorg. particles added to the system to pulverize a precipitate Sb compd. CONSTITUTION:An arom. dicarboxylic acid such as terephthalic acid, or an ester-forming deriv. thereof such as dimethyl terephthalate is esterified with a glycol such as ethylene glycol or butanediol in the presence of 10-1,000ppm (based on the resulting polyester) of an Sb compd. soluble in the glycol and serving as a polycondensation catalyst, such as Sb2O3 or antimony acetate, with addition (which may be made after the esterification reaction) of 10-5,000ppm (based on the metallic Sb of the Sb compd.) of inactive inorg. particles contg. at least 80wt.% oxide, carbonate or sulfate of a metal selected from Ti, Al, Si, Ca, Ba and Bi to prepare a reaction product and an oligomer thereof, which are then polycondensed under reduced pressure at 230-300 deg.C.
