Abstract
PURPOSE: To produce the titled polyester having excellent particle dispersibility, polymn. reactivity and heat resistance, by a method wherein an ethylene glycol slurry contg. a specified silicon oxide and a phosphorus compd. is added to a polyester produced during the production of the polyester.
CONSTITUTION: Silicon oxide having an average particle diameter of 10μ or below and a purity of 90% or higher and 0.1W2mol% (per mole of the silicon oxide) phosphorus compd. (e.g. phosphoric acid or phosphonic acid) are added to ethylene glycol. The mixt. is stirred at high speed and at a temp. of not higher than 100°C to prepare a slurry. Terephathalic acid (or an ester derivative) and a glycol are subjected to an ester exchange reaction in the presence of an polymn. catalyst. Then the above slurry is added to the produced polyester in such a proportion as to give 1W20wt% silicon oxide. The mixt. is subjected to a polycondensation reaction to obtain desired polyester for a rough-surfaced film.
EFFECT: A rough-surfaced polyester film having excellent color tone and gloss is obtd.
