Abstract: High boiling solvent (HBS) lignin is released from plant raw materials by using high boiling alcohol as a solvent. HBS lignin is a novel green material. This paper presents the recent progress of preparation, structure and the basic application research of HBS lignin, especially HBS lignin modified-epoxy resin, polyurethane and polymer additives. Some problems in practical application and the further development of HBS lignin are put forward.
