| Abstract: | Biomass,as a solid natural polymer material,is very difficult to be melted or dissolved.Even so it could be liquefied into solution reactive molecules by organic solvents such as polyols.Furthermore,it could be developed into novel polymer materials such as adhesives and foams.These facts imply that completely new fields of utilization of biomass have been opened.The biomass liquefaction method by polyols,liquefaction mechanism and application of liquefied biomass to polyurethane were reviewed and some opinions to problems occurred is this research field and industrialized development were given. |
