Abstract A series of polyurethane resin samples were synthesized by benzylated wood solution using DBE (dimethyl esters of adipic, glutaric, and succinic acids) and n-butyl acetate as solvent and the adduct of toluene diisocyanate (TDI)/trihydroxymethyl (TMP) propane. FT-IR,WXRD,DTA,TG and DSC are used to analyze the effect of solidifying temperature on microsphase separation and thermal property of the resins. Results show that with the solidifying temperature increasing, the degree of microsphase separation is reduced, the decomposed temperature of hard segment is decreased and the decomposed temperature of soft segment is increased.
