High-pressure viscosity of polystyrene (M w ฯญ 50,000, M w /M n ี 1.06) solutions in toluene and in mixtures of toluene ฯฉ carbon dioxide was measured using a falling cylinder-type viscometer at 320, 340, and 360 K, and up to 35 MPa. Solutions with polystyrene concentrations of 3, 5, and 7 wt % were i

The viscosities of polydimethylsiloxane (PDMS)/CO 2 solutions were measured over the range of pressures of 1-3 MPa and at the ambient temperature. The viscosities were measured by using a specially designed falling ball viscometer (FBV). The Stokes equation was used to determine the viscosities and
## Abstract In the present work, new experimental data are presented on the solubility of carbon dioxide in aqueous piperazine solutions, for concentrations of 0.2 and 0.6 molar piperazine and temperatures of 25, 40, and 70ยฐC respectively. The present data, and other data available in the literatur
