Patent

CA 2127702

The present invention is polyester composition containing crosslinked polymer particles with ester bands at the main chain. The particles are excellent in affinity to polyesters, and so the films formed from the polyester compositions are hard to cause the particles to fall off during; high speed running, and hard to flaw the film surfaces by the particles. Therefore, the present invention can prevent the generation of white powder and the flawing of magnetic faces caused by falling-off particles, and prevent the contamination in the production of films, even though these are problems caused when various conventional particles are added, and is especially suitable for use as products such as magnetic films.
