Notes:
A brief description is given of a new parallel-plate rheogoniometer for normal stress measurements on polymer melts as functions of the rate of shear. A wire-resistance strain gauge is used as the pressure gauge. Measurements are reported on high-density polyethylene. It is found that the time-temperature superposition principle is applicable to the normal stress data as well as to shear stress in steady flow.
