Abstract

PURPOSE: To prepare a polyester film having low frictional coefficient and excellent abrasion resistance, electromagnetic properties, etc., and useful as a base film of magnetic recording tape or an insulating film of a capacitor, by using a specific crosslinked polymer bonded to the polyester through covalent bonds as a raw material.
CONSTITUTION: (A) A crosslinked polymer having an average particle diameter of 0.1W5μ, having a group capable of linking with polyester through a covalent bond, and insoluble and infusible at a molding temperature of the polyester (about 260W 295°C), e.g. a copolymer of a compound having one aliphatic unsaturated bond in a molecule and a compound having two or more aliphatic unsaturated bonds in a molecule as a crosslinking agent, it added to (B) the polyester, pref. polyethylene terephthalate, in the manufacturing of the polyester, and the composition is formed to a film to obtain the objective polyester film containing 0.001W4wt% of the (A) component which is essentially copolymerized to the polyester.
