New pyridine-containing polyimides based on fluorinated gamma-X-pyridylenediamines (X = H, Cl, NH2, O-linkage) and dianhydride 6FDA were prepared by one-step polycondensation in benzoic acid melt. Molecular weight of the polymers enlarges with an increase of nucleophilicity of the pyridylenediamines and solubility of the macromolecules in the reaction medium. 4,4'-Oxydianiline was used as a co-monomer to prepare high-molecular pyridine-containing PI films with good mechanical properties. The polyimides and co-polyimides obtained are soluble in amide solvents, have good thermal and thermooxidative characteristics. Parameters of the polyimides pyrolysis, which provide consecutive elimination of different elements, were found. (C) 2013 Elsevier B.V. All rights reserved.
