Method for preparing cellulose acylate solution, method for producing cellulose acylate film, and cellulose acylate film |
| abstract |
PROBLEM TO BE SOLVED: To provide a cellulose acylate solution at a temperature as close as possible to room temperature without using a chlorine-based organic solvent such as methylene chloride as a solvent for cellulose acylate and without depending on a cooling dissolution method. And a method for producing a cellulose acylate film, and a cellulose acylate film produced by the method. SOLUTION: A mixture containing cellulose acylate in which a hydroxyl group is substituted by an acyl group having 3 or more carbon atoms and containing an organic solvent mainly containing a non-chlorine-based organic solvent is prepared by mixing 10 to 5%. A method for preparing a cellulose acylate solution, comprising a step of treating under a pressure of 000 kgf / cm 2 and a step of treating the treated mixture under a pressure of 0.1 to 10 kgf / cm 2 . |
