Abstract
The present invention provides a thermoplastic lignin polycondensate. The thermoplastic lignin polycondensate produces no fumes and odor even at a normal melt processing temperature. The melt viscosity of the thermoplastic lignin polycondensate can be measured even when heated to 200° C. or more. The thermoplastic lignin polycondensate can be prepared by selectively activating the hydroxyl reactive groups of lignin to suppress the crosslinking reaction of the hydroxyl reactive groups, which allows a linear or grafted linear growth of the lignin polycondensate.
