Title:
METHOD FOR PREPARING ACETYLATED CELLULOSE ETHERS HAVING IMPROVED ANTI-FOULING PROPERTIES, AND ACETYLATED CELLULOSE ETHERS PREPARED BY SAME
Document Type and Number:
WIPO Patent Application WO/2014/088154
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing acetylated cellulose ethers having improved anti-fouling properties and to acetylated cellulose ethers prepared by same. The method for preparing acetylated cellulose ethers having improved anti-fouling properties comprises the steps of: cross-linking cellulose ethers; and acetylating the cross-linked cellulose ethers. The acetylated cellulose ethers prepared by the method may activate the hydroxyl group which is made into blocks by the agglomeration between polymers performed by the materials for cross-linking the cellulose ethers, and may introduce thereto an additional hydrophilic group so as to increase hydrophilic properties, and thus may improve anti-fouling properties when applied to water-treatment membranes.
