摘要

The viscosities of carbon dioxide-impregnated polymers in the literature are currently limited to high shear rates using capillary or extrusion rheometers. This paper uses a rotational rheometer to report data on the zero-shear viscosity of carbon dioxide-saturated polymers. The viscosity drop of a polybutene oil is one and half orders of magnitude at 35°C and 6 MPa, while the zero-shear viscosity of poly(dimethylsiloxane) (PDMS) drops half of an order of magnitude at 30°C and 3 MPa. Efforts are ongoing to measure the CO 2-plasticized viscosity of polystyrene melt.
