摘要：
A method of grafting lignin has been developed which allows 1-phenylethylene (polystyrene) graft copolymers of lignin to be quantitatively made. The grafting reaction is a solution polymerization often run in aprotic, polar, organic solvents. The reaction initiates free-radical grafting of lignin by a redox reaction involving hydrogen peroxide and chloride ion. Grafting changes the solubility and surface properties of lignin, converting it to a thermoplastic. The lignins grafted have been obtained from pine by kraft process and hardwoods by base extraction.
