Cellulose ester, method for producing the same, and optical film |
| abstract |
The present invention provides a method for producing a cellulose ester having a very low content of rutile foreign matter and a cellulose ester produced by the production method. Furthermore, the optical film containing the said cellulose ester is provided. A cellulose ester production method comprising a step of mixing a cellulose ester solution and an alcohol, and further mixing with a poor solvent to precipitate the cellulose ester, wherein the organic ester is used for preparing the cellulose ester solution. A method for producing a cellulose ester, wherein the SP value of the solvent is in the range of 18.5 to 25.0. [Selection figure] None |
