Abstract

PURPOSE: To provide titled film which excels in slip characteristics, has uniform surface with no coarse projection, and can be regenerated and is suitable for use in photograph, magnetic tape, etc., by a method wherein a crosslinked polymer having a specified specific surface area and pore volume is ground to obtain powder which is then incorporated into a polyester.
CONSTITUTION: (i) A monovinyl compd. (e.g. styrene) is copolymerized with (ii) a crosslinking agent (e.g. divinylbenzene) in the presence of (iii) a polymer (e.g. polystyrene) which is soluble in an org. solvent. The resulting copolymer is extracted with an org. solvent to obtain a crosslinked polymer having a specific surface area of not less than 1m2/g and a pore volume of not less than 0.1ml/g. The crosslinked polymer is ground by a jet mill to obtain powder having an average particle size of 0.1W5μ. The powder is added to a polyester-producing reaction system to obtain a polyester compsn. contg. 0.001W4wt% of the powder. The polyester compsn. is molded into film.
EFFECT: The grinding of the crosslinked polymer can be carried out in a short time.
USE: Films for metallizing, condenser, photoengraving and mold releasing.
