METHOD FOR PRODUCING THERMOPLASTIC FILM AND OPTICAL COMPENSATION FILM FOR LIQUID CRYSTAL DISPLAY PANELS PRODUCED BY USING THE METHOD |
摘要 |
There is provided a method for producing a thermoplastic film, which can suppress the occurrence of residual strain in the film caused by the polishing roller method to prevent the occurrence of stretch non-uniformity in stretching operation and provide a film that has excellent optical characteristics. The molten resin extruded from a die into a sheet is fed between a pair of polishing rollers and cooled while being held and pressed between them so that a cellulose acylate film is formed. The surface of the polishing roller is made up of a fluorine resin.
