Abstract
Abstract This invention provides novel quaternary ammonium ethers of polygalactomannan having a degree of substitution between about 0.01 and 3.0, and further provides a process for producing quaternary ammonium ethers of polygalactomannan gums by contacting solid polygalactomannan gum with a haloalkyl-substituted quaternary ammonium compound under alkaline conditions in an aqueous solution of water-miscible solvent.
