Nanocomposites of extrusion-type Surlyn ionomer and intercalated sodium-type of montmorillonite were compounded on a KO-kneader and measured on a modified capillary rheometer for strain rate vs. pressure dependencies of shear and elongational viscosities for various clay concentrations (0,1,3,5 wt %). The modified White-Metzner model was employed to simultaneously fit the viscosity data and determine pressure coefficients, which have been found to decrease with the loading level of the nanocomposites

Na speciálně upraveném kapilárním reometru byla měřena smyková a elongační viskozita pro nanokompozitní materiál Surlyn/Montmorillonite. Byla užita modifikovaná Whiteova-Metznerova metoda pro současné vyhodnocení viskozity a určení tlakových koeficientů
