A high-melting polymer was obtained which is capable of film formation on the boundary of the separation of the phases. The influence of concentrations of original monomers, their relationship, and the nature of the applicable organic solvents on the yield, specific viscosity and film formation was clarified. It was established that the synthesized polymers have crystalline structure. It was shown that the highest temperature of fusion 345 - 350C is possessed by a polymer obtained on the basis of dian and terephthalic dichloroanhydride. Author
