Abstract
Aim. We consider the rheological behavior of a rigid-chain polymer solution, which forms a lyotropic nematic crystal at high concentrations. Methodology. An approximation of the experimental data of the non-Newtonian flow is carried out on separate intervals of the shear rate. Results. We present the equations of the structural rheological model that relate rheological properties to the structure of the polymer solution. Research implications. Equations are proposed that can approximate the experimental data on separate intervals of the shear rate corresponding to a certain structural state of the polymer solution.
