    Notizen: The dynamic properties of low molecular weight polyisobutylene and silicone oils have been investigated over a range of frequencies and temperatures. When subjected to oscillating stresses, these materials behave as though they had a shear modulus as well as a viscosity. Dynamic viscosities and rigidities have been determined at frequencies between 10 and 100 cycles per second and at temperatures between -50° and +60°C. Falling ball viscosities were also obtained over the same temperature range. In general, moduli increase with increasing frequency and decreasing temperature while dynamic viscosities decrease with increasing frequency and increasing temperature. At room temperature and above, the dynamic viscosity varies very little with the frequency and is essentially the same as the falling ball viscosity. At lower temperatures the dynamic viscosity decreases considerably with increasing frequency but extrapolates to the falling ball viscosity at zero frequency. If these materials are regarded as complex Maxwell liquids, the dynamic rigidities and viscosities may be written as functions of a “reduced frequency” equal to the frequency multiplied by an exponential of a constant divided by the absolute temperature. This constant can be evaluated from the slope of the linear plot of the logarithm of the falling ball viscosity over the absolute temperature versus the reciprocal of the absolute temperature. For a given material a single constant suffices to bring the data at all frequencies and temperatures into a single plot similar to that used by Ferry.
