New poly (ester-amide-imide)s containing aminoacids and4,4’- (diamidodibenzo) sulfone units were prepared and their solubility and viscosity were evaluated. The viscosities of polyamides are in the range of 0.43-0.47. These polyamides showed good solubility in common organic solvents. Theoretical calculation shows the high free volume of polymer chains.
