Conclusions

  1. 1.

    A new method has been developed for the synthesis of high molecular aromatic polyimides — a one-step high-temperature polycyclization in solution, which substantially simplifies the synthesis of such polymers and their application.

  2. 2.

    An idea of the molecular weights and coefficient of polydispersion of polyimides was obtained for the first time, with soluble polydiphenylenphthalidepyromellitimide as an example.

  3. 3.

    Certain physicochemlcal properties of polyimides of anilinephthalein and anilinephthaleinimide were studied, and it was shown that these polymers possess a valuable complex of properties: high mechanical indices, excellent thermal stability, which in conjunction with the good solubility of these polyimides, makes them extremely promising for practical utilization.

  4. 4.

    The question of the influence of various structural factors upon the solubility of polyimides was discussed, and it was shown that the solubility of polyimides of anilinephthalein and anilinephthaleinimide is due to the large size of the phthalide and phthalimidine side groups and to their polarity.
