ABSTRACT:
The invention relates to a method for modifying cellulose ethers. The inventive method is characterised in that a cellulose ether having a humidity content of between 5 and 90% is intensively mixed with between 0.1 and 5 wt. %—in relation to the dry cellulose ether—of an additive or an additive mixture in the form of an aqueous or organic suspension or solution, at temperatures of between 20 and 100° C., and the mixture obtained is then dried.
