Preparation of Mixed Ethers by Reaction of Carboxymethyl Cellulose with Urea and Their Physicochemical Properties

摘要

The conditions of preparation of mixed cellulose ethers containing carboxymethyl and amide groups by reaction with urea were examined with samples of commercial carboxymethyl cellulose and that prepared from flax cellulose as examples.The water solubility of the resulting products and their sorption activity toward copper ions were examined in relation to the amount of amide groups introduced.
