Conditions for the production of fibrillar fiber-like particles from solutions of polyesterurethane by phase separation method in a nonsolvent medium were studied. The rheological characteristics of polyesterurethane solutions, which have an effect on the flow of the polymer solution in the spinning process in a nonsolvent medium under turbulent hydrodynamic conditions, were investigated. The effect of the type of nonsolvent (precipitant) on the structure and the mean diameter of the fiber-like particles were studied.
