The description of the structure of dispersion-filled polymer composite materials (DFPCM) and the main parameters characterizing it are considered. An analysis of a number of modern models used to describe the rheological properties of DFPCM is carried out. A generalized mathematical model is proposed that links relative viscosity with the parameters of the dispersion structure. Using the example of DFPCM with different average particle sizes (glass microspheres, marshalite, and white carbon), it is shown that the presented model allows, based on structural parameters, to describe the dependence of the effective viscosity of the studied dispersions over the entire range of filler content for all dispersed systems with different polymer matrices and fillers. The application of this approach in technological practice allows the viscosity values of melts to be estimated based on the parameters of a given type of structure of a dispersion-filled polymer composite material.
