Abstract

Polyimides containing imide and (p-phenoxy)imide side groups were obtained by the interaction of new aromatic tetramines, bis[3-amino-4-(p-aminophenoxy)]arylenes, with equimolar amounts of aromatic tetracarboxylic acid dianhydrides and twofold molar amounts of aromatic dicarboxylic acids anhydrides. Structures and properties of the final polyimides depend on the nature of starting monomers and subsequent introduction of monomers to the reaction mixtures. Polyimides thus obtained demonstrate good solubility in organic solvents, high glass transition temperatures and good stability.
