GRAFT COPOLYMERS OF LIGNIN (2-PROPENAMIDE)-(1-PHENYLETHENE) METHOD OF MAKING SAME AND USES THEREFORE

摘要

A graft copolymer of lignin-(2-propenamide)-(1-phenylethylene) having a central lignin network and at least one grafted side chain, R, having randomly repeating units of formula (I) in combination with repeating units of (1-phenylethylene) (II) 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 is in the range of 50 to 300,000, such that the total copolymer molecular weight is in the range of 15,000 to 30,000,000.
