METHOD FOR FORMING FILM OR SHEET OF CYCLIC OLEFIN POLYMER

Japanese Patent JP2002079529

A

To provide a method for forming the film or sheet of a cyclic olefin polymer by a solution casting method which is excellent in moistureproofing properties, tearing easiness, unsealing easiness, incineration easiness, etc., and is easy of thickness control and solvent removal and the sheet or the film excel lent in appearance and heat resistance which is obtained by the method.

In the solution forming method, a cyclic olefin polymer solution comprising at least one cyclic olefin polymer having specified structure and the first solvent is cast on a support, the solvent is removed, and the polymer is coagulated. In the method, the cast polymer is contacted with the liquid or vapor of the second solvent which can not dissolve the polymer substantially.

JPH0617993	INDUSTRIAL APPLICABILITY [Title of Invention] Silver halide photographic photosensitive material having excellent antistatic ability and adhesive resistance.
JP2000066339	PACKAGED BODY OF SHEET TYPE PHOTOGRAPHIC FILM AND DISPLAYING METHOD OF PHOTOGRAPHIC FILM PACKAGE
JP2000066340	METHOD FOR CONTROLLING PRODUCTION OF PHOTOGRAPHIC FILM CARTRIDGE
