Abstract
This invention relates to an improvement in the process for the preparation of a stable aqueous electrolyte-containing cellulose ether suspension, wherein an inherently water-soluble cellulose ether is added, in the form of solid particles, to an aqueous solution of an electrolyte and uniformly distributed therein, the improvement comprising using a non-ionogenic cellulose ether and adding alumina to the suspension.

In the process for the preparation of a stable aqueous electrolyte-containing cellulose ether suspension, wherein an inherently water-soluble cellulose ether is added, in the form of solid particles, to an aqueous solution of an electrolyte and uniformly distributed therein,
- the improvement comprising using a non-ionogenic cellulose ether and adding alumina to the suspension, and wherein the amounts of the components of said suspension are about 0.5 to 40 percent by weight of said non-ionogenic cellulose ether, about 4 to 12 percent by weight of electrolyte and about 0.1 to 10 percent by weight of alumina, calculated on the weight of the electrolyte solution.
