Fragmentary polyamicacids on the basis of industrially made poly(4,4’-diaminodipheniloxide)piromellitamicasid and oligoamidoacid, received by polycondensation of 4,4’-diaminodiphenyloxide and dianhydride 4,8-diphenil-1,5-diazodicyclic-/3,3,0/-octane-2,3,6,7-tetracarboxylic acid has been synthesized with their subsequent chemical imidization. Unlike initial poly(4,4’-dipheniloxide)peromellitimide synthesized block polyimides possess solubility in polar aprotic solvents. For explanation of their solubility calculations of parameters of conformation of constitutional repeating units of macromolecules by computer modeling has been carried out.
