  Abstract:

  Ionic Liquids (ILs) were suggested for polycondensation   processes, especially for polyimides synthesis. The influence of   various reaction parameters including IL’s cations and anions   nature, monomer structure and concentration, reaction   temperature, upon polyimide molecular weight (hinh) was   investigated. The possibility of process activation by the   application of IL’s small additives in one step polyimide   synthesis in common organic solvents was demonstrated. The   peculiarities of C-H…Br contacts in solid state were carried out   using single crystal X-ray diffraction data. Various high   molecular weight polyimides including commercial and sulfonated   ones have been obtained in quantitative yields with inherent   viscosities range from 0.10 to 2.17 dL/g.
