Abstract
Optical and hydrodynamic properties of poly(diphenylene sulfone tereph thalamide) in sulfuric acid were studied using flow birefringence and viscometry. Optical anisotropies of the molecular segment and monomer unit and equilibrium rigidity of the entire macromolecule were evaluat ed from the experimental plot of the optical shear coefficient versus molecular mass. The macromolecules of the studied heterocyclic polyami de were found to possess the conformation of a kinetically rigid coil.
