A technology of obtaining combined polymeric products at layer-sector co- extrusion in various molding channels was suggested. Patterns of combined polymer co-extrusion processes in molding channels at layer-sector combination were examined. Dependences to allow definition of polymer melts flows hydrodynamic characteristics at layer-sector co-extrusion in molding channels were suggested. Calculated flow rate characteristics according to the suggested dependences and the experimental data during layer-sector polymers flow in molding channels were compared.
