<p>The present invention relates to a polyester composition comprising polyester and 0.005 to 1% by weight, based on said composition, of particles having an average particle size of 0.01 to 2 mu m which comprises a crosslinked polymer having ethylene glycol unit in the molecular chain thereof, or 0.005 to 1% by weight, based on said composition, of multi-layer organic particles having an average particle size of 0.05 to 3 mu m which comprises a core organic particle and a coating layer of said crosslinked polymer, the loss in weight after heat treatment at 300 DEG C for 30 min of said crosslinked polymer particles and said multi-layer organic particles being not higher than 30%. The film obtained from the polyester composition of the present invention has an excellent running property, and abrasion resistance, and is quite useful for various practical uses. Also the film obtained from the polyester composition of the present invention has an excellent transparency and can be used for bottles or similar packaging materials.</p> |
