摘要： A particulate cellulose derivative is obtained in a process of grinding and drying a moist cellulose derivative which comprises the steps of A) providing a cellulose derivative having a moisture content of from 60 to 95 percent, based on the total weight of the moist cellulose derivative, B) grinding and partially drying the moist cellulose derivative in a gas-swept impact mill; and C) contacting the ground and partially dried cellulose derivative with an additional amount of a drying gas outside the gas-swept impact mill. The obtained particulate cellulose derivative has a high untapped bulk density and a good flowability.

摘要： The present invention relates to a process for the preparation of a water-moist cellulose ether composition, characterized in that water-soluble polymeric additives which contain anionic groups (WSAP), or corresponding additive mixtures, are added to the cellulose ether composition. The invention furthermore relates to water-moist cellulose ether compositions which can be prepared by such a process, and to corresponding milled and dried cellulose ether compositions. The invention also relates to the use of these WSAP or corresponding WSAP mixtures for improving the transportability of water-moist cellulose ether compositions in conveying units.
