Development of discrete mathematical models of mixing and forming processes at preparation of new polymeric compositions.

The discrete mathematical models of processes of mixing at the unisothermal flow of fusions of polymeric compositions in the mixers ducting of static and dynamic types taking into account the change of their rheological properties from a deformation-temperature condition is developed. A method of the numeral computations of mixing processes of polymer fusions with other components in the mixers ducting of base configurations of extrusion and molding equipment is developed. The mathematical model of profiling of the forming ducting taking into account dependence of properties of compositions on the technological regime, and also from time of stay under the action of technological factors is developed…
