Synthesis of 4,4′-bis(4-aminophenoxy)benzophenone and polyimides based on this compound

Article abstract of DOI:10.1007/BF01435795

Synthesis of 4,4′-bis(4-aminophenoxy)benzophenone was performed starting from chloral. Various polyimides were obtained by reactions of 4,4′-bis(4-aminophenoxy)benzophenone with aromatic tetracarboxylic acid dianhydrides. Some of the polyimides obtained are crystalline compounds.
