Beschreibung
Zusammenfassung:	- Improving transportability of a water-moist cellulose ether composition (I) in a conveying unit, comprises: (a) providing a starting material having a water-moist cellulose ether or a cellulose ether mixture having a moisture content of 25-75 wt.%; (b) optionally adding and mixing in of water and/or optionally adding and mixing in of further additives, (except for water-soluble polymeric additive which contains anionic groups (WSAP)), to the starting material, and (c) adding 0.001-2 wt.% of WSAP or WSAP mixture to the composition obtained in step (a) or in steps (a) and (b), to obtain (I). Improving transportability of a water-moist cellulose ether composition (I) in a conveying unit, comprises: (a) providing a starting material comprising a water-moist cellulose ether or a cellulose ether mixture having a moisture content of 25-75 wt.%, based on the total mass of the starting material; and (b) optionally adding and mixing in of water and/or optionally adding and mixing in of further additives, (except for water-soluble polymeric additive which contains anionic groups (WSAP)), to the starting material, and (c) adding 0.001-2 wt.% of WSAP or WSAP mixture, based on the dry mass of the cellulose ether composition to be prepared, to the composition obtained in step (a) or in steps (a) and (b), to obtain (I) having a moisture content of 45-85 wt.% based on the total mass of the cellulose ether composition.
