Abstract
PURPOSE: To obtain the said film excellent in sliding property, wear resistance and poor in elution in which inert particles with specific particle diameters which are deposited by a reaction system and bridged macromolecular fine grains with specific particle diameters which enter into a covalent bond with polyester are contained.
CONSTITUTION: Bridged macromolecular fine grains (A) are obtained by a method wherein copolymers made from monovinyl compounds having one aliphatic unsaturated bond in a molecule and compounds having two or more aliphatic unsaturated bonds in a molecule as a bridging agent are pulverized into average particle diameters of 0.1W5μ. Terephtalic acid (ester formation derivatives) (a) and ethylene glycol (b) are reacted in the presence of an alkali (earth) metal compound to obtain a polyester (C) in which inert molecular particles (B) with average particle diameters of 0.5W5μ are deposited. Both (a) and (b) are reacted under the presence of (A) to obtain a polyester (D) which brings (A) into covalent bond. Then, (C) and (D) are mixed so that (A) takes 0.001W4% by weight and (B) takes 0.01W0.6% by weight in order to form the film.
