Abstract

PURPOSE: To provide the titled polyester which does not cause trouble in spinning and stretching system, by a method wherein a glycol-contg. dispersion medium colloid of silica treated under specified conditions, is reacted with a dicarboxylic acid.
CONSTITUTION: At least 10wt% of glycol is added to an aq. silica sol contg. 0.5W 10wt% (based on the weight of a polyester produced) of fine silica particles having an average particle diameter of 100mμ. The mixt. is stirred for at least 2hr to obtain a glycol-contg. dispersion medium colloid of silica. Then a dicarboxylic acid and, if necessary, glycol are added to the colloidal silica. The mixt is subjected to an esterification reaction and then to a polymn. reaction to obtain a silica-contg. polyester.
