摘要：

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.
