Abstract

Two optically active DIANHYDRIDEs were prepared from the reaction of L-aspartic acid with either pyromellitic DIANHYDRIDE (PMDA) or benzophenone tetracarboxylic DIANHYDRIDE (BTDA) and subsequent transformation of tetraacids to DIANHYDRIDEs using thionyl chloride. Solution POLYCONDENSATION reaction of the prepared DIANHYDRIDEs with different aliphatic and aromatic DIISOCYANATEs (MDI, PPDI, NDI, HMDI, H12MDI and IPDI) resulted in the preparation of twelve novel optically active POLYIMIDEs. The optimal conditions for polyimidations (reaction time and temperature programming) were obtained via study of the model compounds. The resulting POLYIMIDEs showed inherent viscosities in the range of 0.18-0.55 dL/g and showed good solubility in polar aprotic solvents. The monomers, model compounds and polymers were characterized by FTIR, 1HNMR spectroscopies and elemental analysis, and their physical and optical properties were studied as well.
