Graft copolymers of wood pulp and 1‐phenylethene. I. Generality of synthesis and proof of copolymerization

摘要

AbstractA method of grafting lignin‐containing materials is now known that allows 1‐phenylethylene (styrene, 100‐42‐5) graft copolymers of a lignin source to be quantitatively made. The grafting reaction is a solution polymerization often run in aprotic, polar, organic solvents. Grafting changes solubility and surface properties of the lignin‐containing material. The lignin‐containing materials grafted are unbleached wood pulps produced by chemical, thermal, and mechanical pulping. Grafting wood pulp produces a wood‐reinforced, thermoplastic composite. © 1993 John W
