The novel bis(2, 4-dihydro-2H-3-(4-N-maleimido) phenyl-1, 3-benzoxazine)isopropane (BMIPBI) was synthesized from maleic anhydride, p-nitroaniline, formaldehyde and 2,2-bis(4-hydr -oxyphenyl)propane by a few steps reactions via the N-(4-nitrophenyl)maleimide(NPMI), N-(4-amin -ophenyl)maleimide(APMI),1,3,5-three(4-(maleimido)phenyl)-1,3,5-triazine(TMIPT)intermediate production. The chemical structures of BMIPBI were confirmed by 1H-NMR, FT-IR and EA. The results show that the production was the target object BMIPBI. The synthesized condition had been studied too. The BMIPBI was a loosened yellow solid and the yield of product was 58.8%.
