High-pressure viscosity of polystyrene (M w ϭ 50,000, M w /M n Յ 1.06) solutions in toluene and in mixtures of toluene ϩ 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
