The research on the influence of the concentration of the combined nano-dispersing additive of titanium oxide / silica (TiO2/SiO2) on the rheological properties and the structure-formation processes in a mixture of polypropylene / co-poliamid (PP/CPA) has been conducted. Established that during the flow of melt the allocation of components on phases with the formation of liquid jets (PP microfiber) in the matrix spa takes place
