A NOTE ON THE VARIATION WITH TEMPERATURE OF THE INTRINSIC VISCOSITY OF GR-S IN BENZENE

Open publisher page 0 citations

Abstract

The intrinsic viscosity, [η], (as well as the intrinsic flow time, [t], and the intrinsic kinematic viscosity, [ν]) of normal GR-S in benzene has been shown to be independent of temperature, over the range 10° to 55 °C, within the experimental precision [Formula: see text]. In this range of temperatures, also, the functions [Formula: see text] and [Formula: see text] are independent of concentration (up to at least 0.3%), and may therefore be used in the one-point determination of [t] and [ν].
