Conclusions
-- The flow mechanism and viscosity properties of melts of polycaproamide concentrates of dyes (PDC) are determined by the nature, composition, and content of the coloring agent.
-- The characteristics of PDC which are used in industry do not give complete information about the rheological properties of their melts.
-- Industrial specimens of PDC which are complex multicomponent systems behave as uniform compositions over a wide range of stresses and shear rate gradients.
