| Abstract: | Molecular hydrodynamics and optical methods have been employed to study the properties of molecules of polybenzimidazoles
in 96% H2SO4 and to determine their molecular, conformational, and dynamo-optical characteristics. The temperature dependence has been
investigated for the intrinsic viscosity. The equilibrium rigidity of molecular chains has been estimated for the examined
polybenzimidazoles. |
