In the prepn. of the filler-dispersible polyester by esterexchanging reaction and polycondensation of terephthalic acid or its derivs. with glycol, ethylene glycol slurry which contains 0.01-20 wt.% the inorganic filler distributed having up to a max. diameter of 10 microns (pref. 2-7 microns) with respect to the polymer and 0.05-10 wt.% the metallic salts of phosphoric acid or phosphorous acid with respect to the filler, is added. The polyester has good properties of thermal-resistance, processpassing properties and high-luster.
