Abstract:
The present invention relates generally to a method for dispersing a dry cellulose ether powder in an aqueous solution without forming lumps using powder handling and mixing devices. The cellulose ethers can be cross-linked with an aldehyde cross-linker. An acid or partially neutralized acid is used to improve the solubility.
