Zusammenfassung:	PROBLEM TO BE SOLVED: To plan improving smoothness, wear resistance, flavor, adhesion and impact resistance by adding certain indeterminate and/or coherent inorganic particles to polyesters. SOLUTION: Indeterminate and/or coherent inorganic particles which have water contents of 0.5% or less and a peak between 50-80 ppm in spectra at C-NMR measurements, is obtained by heat mixing at least 50 deg.C for at least 5 min inorganic particles which are BET specific surface of 30-1,000 m /g of at least a one compound selected from silicon dioxide, aluminum oxide, calcium phosphate, magnesium oxide, metal carbonates and silicates, and which are an average secondary particle diameter of 0.001-10 μm, with 0.001-50 wt.% of glycol compounds. An objective polyester composition is prepared by adding 0.0001-10 wt.% of indeterminate and/or coherent inorganic particles, and is necessary, 1-500 ppm of at least one element selected from germanium, antimony and titanium, with polyesters which have diethylene glycol contents of 0.5-5 wt.% and a melting point of 100-270 deg.C.
