CELLULOSE ACYLATE FILM AND METHOD FOR PRODUCING THE SAME AND ORIENTED CELLULOSE ACYLATE FILM

摘要

PROBLEM TO BE SOLVED: To provide a cellulose acylate film having good planar properties and excellent in extensibility. SOLUTION: The method for producing the cellulose acylate film comprises activating cellulose with a 2-7C carboxylic acid, reacting the activated cellulose with a carboxylic acid anhydride to prepare cellulose acylate and filtrating and casting the cellulose acylate to form a film.
