A furfuryl ester-terminated butylene succinate oligomer (FBSO) with Mn 1800 and Mw 2800 was synthesized by the condensation of furfuryl alcohol with a carboxyl-terminated butylene succinate oligomer. The reaction of FBSO and 1,1′-(methylenedi-4,1-phenylene)bismaleimide (BMI) in chloroform at 60°C for 48h yielded an exo-rich Diels–Alder (DA) adduct ((P(FBSO-BMI)) with Mn 9000 and Mw 15500. The gel permeation chromatography analysis of the products of heating a reaction mixture of P(FBSO-BMI) in dimethylformamide (DMF) at 120°C for 1h revealed that FBSO and BMI are quantitatively recovered by the retro DA reaction. Maleimide/phenyl-substituted oligomeric silsesquioxane (MPOSS) was synthesized by the reaction of maleimidemethyl 3-(triethoxysilyl)propylcarbamate and triethoxyphenylsilane in the presence of hydrochloric acid. The DA reaction of FBSO and MPOSS in DMF at 60°C for 48h gave a partially crosslinked hybrid composite insoluble in general organic solvents. When the hybrid composite was heated in DMF at 140°C, the retro DA reaction proceeded smoothly. The hybrid film prepared by casting a DMF solution of FBSO and MPOSS and subsequently heating at 60°C for 48h had a much higher flexural strength than FBSO did.
