摘要

Abstract

A diamine monomer

-phenylenedioxybis(5-amino-2-pyridine) was synthesized

via

reduction of a dinitro compound

-phenylenedioxybis(5-nitro-2-pyridine)

producing a series of new polyimides from this diamine and various commercially available aromatic dianhydrides

via

conventional two-stage processes. The resulting polyimides are able to form tough and transparent films

with decomposition temperatures in the range of 529–551 °C

and can be dissolved in organic polar solvents. Meanwhile

these polyimides can be degraded in a hydrazine hydrate medium

a degradation mechanism proposed by analyzing the degradation products suggests that the degradable properties could be attributed to the phenyl-2-pyridyl ether structure in the polymer. In addition

the transformation of the compound structure from dinitro compound to damine monomer in the synthetic process is discussed in respect to X-ray structure.
