Abstract: This invention relates to an improvement in the method for the cold-milling of a cellulose derivative, in which the cellulose derivative is cooled by means of liquid nitrogen until it becomes brittle and the thus cooled cellulose derivative is milled in a mill, the improvement comprising cold-milling a cellulose derivative which is soluble or swellable in water and has a water content of between 40 and 150 percent by weight, based on its dry weight, and which is, at 20 DEG C, able to absorb, during swelling, more than 150 percent by weight of water, based on its dry weight.

Abstract: Disclosed is a process for the chemical modification of a water-soluble cellulose ether, which comprises reacting the ether with a chloroformic acid ester in an aqueous organic medium containing alkali hydroxide, whereby the cellulose ether is rendered at least partially insoluble in water. The modified cellulose ether may be easily dispersed in water and redissolved to form a smooth solution of the original water-soluble ether by adding sufficient alkali to the dispersion to reuse its pH to at least about 11, preferably to about 12.
