| description | PROBLEM TO BE SOLVED: To provide a cellulose ether exhibiting delayed dissolution. SOLUTION: This process for producing the cellulose ether exhibiting the delayed dissolution in water comprises steps of (a) treating a wet cellulose ether with a dialdehyde solution and (b) drying and fine pulverization of the cellulose ether. An aqueous solution of a salt is added simultaneously or together with the dialdehyde solution so as to uniformly set the pH of the cellulose ether at 6.0-8.0. COPYRIGHT: (C)2003,JPO |
