Abstract

The behavior of dilute solutions of cardo polybenzimidazoles based on 3,3′4,4′-tetraaminodiphenyl ether; 3,3′,4,4′-tetraaminodiphenyl sulfone; and 4,4′-diphenylphthalidedicarboxylic acid in solvents of various natures has been studied by the methods of dynamic light scattering, sedimentation, and viscometry. All of the polymers have been found to contain a microgel fraction. For each fraction, the diffusion coefficient and the particle size are determined. The experimental characteristics of macromolecules correspond to the conformational rigidity calculated by a computer simulation procedure.
