概要	Difurfurylidene diglycerol (DFDG) was synthesized by the reaction of furfural and diglycerol, both of which can be derived from renewable resources. The NMR analyses revealed that DFDG is a mixture of stereoisomers. Diels-Alder (DA) polymerization of equimolar amounts of DFDG and 4,4'-bismaleimidodiphenylmethane (BMI) at 60 degree C for 48 h in chloroform afforded a bio-based linear polyimide (DFDG-BMI) with Mw of 5,400. The Mw of the polyimide obtained by the reprecipitation of DFDG-BMI (pDFDG-BMI) was 7,900. The X-ray diffraction and polarized optical microscopic analyses revealed that pDFDG-BMI is a crystalline polyimide. The differential thermal analysis revealed that pDFDG-BMI had a melting temperature at 126 degree C, and broad endothermic peaks at around 140-170 degree C due to retro DA reaction. The retro DA depolymerization of pDFDG-BMI in N,N-dimethylformamide smoothly proceeded at around 100-120 degree C to regenerate the corresponding monomers.
