  摘要：

  An efficient route towards the synthesis of 2,5-diamino-2,5-dideoxy-1,4-3,6-dianhydroiditol 4 has been developed resulting in significant improvements in both isolated yields and purity when compared to literature procedures. As a consequence, resin-grade 2,5-diamino-2,5-dideoxy-1,4-3,6-dianhydroiditol 4 has become available for laboratory scale step-growth polymer synthesis. Additionally, an interesting renewable chiral 2-amino-2-deoxy-1,4-3,6-dianhydroiditol 10, has been isolated. (C) 2010 Elsevier Ltd. All rights reserved.

  Novel partially bio-based polyimides were prepared from 2, 5-diamino-2, 5-dideoxy-1, 4: 3, 6-dianhydrosorbitol (diaminoisosorbide, DAIS) dihydrochloride, 2, 5-diamino-2, 5-dideoxy-1, 4: 3, 6-dianhydroiditol (diaminoisoidide, DAII) dihydrochloride, and various dianhydrides via a conventional one-step method in m-cresol. Inherent viscosity values of these polyimides spanned a range of 0.5 -1.5 dL/g. Flexible and transparent films can be easily cast from their corresponding solutions. The chemical structures and properties of isohexide-derived polyimides were fully characterized by using a variety of analytical techniques. The results revealed that the thermal and mechanical properties of isohexide-derived polyimides were similar to those derived from petrochemical-based diamines. Moreover, these polyimides exhibited good optical transparency, and optical activity. The good overall properties of isohexide-derived polyimides can be contributed to the incorporation of unique isohexide moieties that were rigid, thermally stable, fully aliphatic and chiral.
