Further studies on homopolymers and copolymers resulting from the reaction of polymaleic anhydride with alcohols and amines

摘要: Polymaleic anhydride prepared by γ-rays irradiation of maleic was used as a reactive polymer and reacted with certain long-chain aliphatic amines and/or alcohols well the mesogenic biphenylamine. The homopolymers copolymers that were prepared, i.e., derivatives N-alkyl polymaleamic acid, monoesters polymaleic or mixed amide-ester derivatives, primarily investigated far their property to show thermotropic liquid crystalline character is concerned. By this investigation structural features for exhibition mesomorphism these polymers determined.
