Abstract
Aromatic polyimides containing side azobenzene groups has been synthesized by low-temperature solution polycondensation of certain aromatic dianhydrides with aromatic diamines containing preformed side azobenzene groups followed by chemical imidization at 100 °C în the presence of pyridine and acetic anhydride. The glass transition temperature of these polyimides is in the range of 185-230°C and the average weight molecular weight is in the range of 16000-129000. Keywords: polyimides, side azobenzene groups, glass transition
