A functionalized lignin is described. The functionalized lignin comprises lignin containing resident constituents comprising at least one of hydroxyl, methoxyl, carbonyl, carboxy and sulfonate moieties, as well as aromatic components. At least one of the resident constituents is functionalized with at least one functionalizing compound having a moiety reactive with at least one of the resident constituents. The functionalizing compound contains one or more functional moieties comprised of: anhydrides, esters, alkyl silanes, alkyl alkoxy silanes, alkyl halo silanes, amino silanes, alkoxy silanes, organoalkoxysilane thiols, and silanes; and the functional moieties which contain at least one functional group comprised of: amine, acrylate, methacrylate, thiol, isonitrile, nitrile, isocyanates, allyl, olefin, alkyne, ester, epoxide, sulfide, haloalkane, perhaloalkane, amide, carbonate, carbamate, sulfonyl, azidosulfonyl, sulfolane, hydroxyl, and aryl functional group.
