Based on the graft copolymerization reactions of lignin and vinyl monomers, a series of graft copolymers of wood pulp and styrene (1-phenylethene) has been synthesized. The wood pulps used in this research are unbleached products produced by chemical

Graft copolymers of lignin, made by free radical graft copolymerization of 1-phenylethene on lignin, increased the contact angle of water on birch wood (Betula papyrifera) and decreased the critical surface tension of the wood when coated onto the wo

A chemical modification method has been developed to convert lignin into lignin–styrene graft copolymers. The graft products are macromolecular surface active agents because, within each molecule, a hydrocarbon sidechain has been grown off of a nat
