WebFeb 12, 2024 · Polycarbonate (PC), an engineering plastic, has excellent mechanical strength and toughness. Moreover, this transparent polymer material can be used in fields where materials require mechanical properties and transparency. Nevertheless, PC is known to have a high melt viscosity. Moreover, blending with polystyrene (PS), an … Webzero-shear viscosity for pure PS and pure PVME, a simple viscosity blending law was applied to calculate the PS-PVME blend viscosity values. From each blend composition, a common monomeric friction factor was calculated. These values, reported in ref 22b for two temperatures (105 and 125 °C), were used here for a second set of calculations
