  • Abstract
    Two series of aromatic polyimides containing side azobenzene groups have been synthesized by low-temperature solution polycondensation of certain aromatic dianhydrides with aromatic diamines containing preformed side azobenzene groups followed by chemical imidization at 100degC in the presence of pyridine and acetic anhydride. The resulting polyimides were studied by spectral methods (UV, IR) and thermal analysis.
