|Abstract:||The viscosity of propylene was measured by use of an oscillating disk viscometer in the pressure range below the saturated vapor pressure of propylene at 25, 50 and 75℃, up to about 43×10^5 Pa at 100℃, and up to about 56×10^5 Pa at 125℃. The accuracy of the measurements was estimated to be within ±0.5%. An initial decrease in viscosity in the low density region could not be observed. The initial density dependence of viscosity, α'=η_0^-1(∂η/∂p)_p→0, of propylene was determined from the experimental values and compared with the calculated α'-values, where η is viscosity; p density; and η_0 the viscosity extrapolated to zero density. α' increased with a decrease in a polarity parameter, δ, and with a rise in temperature in the correlation between α' and a polarity for six polar gases.|
