Abstract

Nuclear magnetic resonance (NMR) was used to determine the T₂ NMR relaxation times of silicone oils. T₂ characterizes the molecular mobility of fluids. The T₂ times, furthermore, correlate with both the zero-shear-rate viscosity and the molecular weight of the corresponding silicone oil. Thus NMR provides the possibility of determining simultaneously the zero-shear-rate viscosity and the molecular weight of silicone oils by means of T₂ experiments.
