Water soluble graft copolymers of lignin, methods of making the same and uses therefore

摘要

A water-soluble graft copolymer of lignin-(2-propenamide)-(4n,4n-dimethyl-4-ammoniumhept-1,6-diene chloride) having a central lignin network and at least one grafted side chain, R, having randomly repeating units of the formulas: such that the central lignin network has a molecular weight of about 1,000 to 150,000 and the total number of randomly repeating units in the grafted side chain or chains is in the range of 5 to 300,000 such that the total copolymer molecular weight is in the range of 1,000 to 30,000,000.
