| Outline of Final Research Achievements |
Liquefaction of biomass in the presence of glycerol or commercial polyols manufactured from glycerol and propylene oxide could be successfully done. Acceptable conditions for obtaining excellent biopolyols under usages of homogeneous, or solid acid catalysts, or non-catalyst system could be made clear. It was demonstrated that physical properties of the bio-polyuretane foams could be improved by being composited with succinic acid monoesterified cellulose nanofibers. The simultaneous liquefaction of constarch in the presence of a small amount of hydroxypropylated cellulose gave polyols, which could result in polyurethane foams powered by better mechanical properties and thermal stabilities. It was made clear that the liquefaction done by our current studies have advantages over that through oxypropylation reaction.
