Abstract
Alkyl ethers of polygalactomannans wherein the alkyl groups contain 1 to 4 carbon atoms are further modified with long chain aliphatic epoxides wherein the long chains contain 8 to about 28 carbon atoms. The resulting derivatized polygalactomannans are particularly useful as thickening agents for aqueous systems.
