Notes:
From a measurement of the dielectric increment of methylcellulose in water, including the frequency dependence of this increment, the dielectric relaxation time spectrum has been determined and represented quantitatively by a formula containing three parameters τor, νAh, and θq, each of which can be obtained from earlier published viscosity and birefringence of flow data. On the basis of this relaxation time spectrum, the Cole-Cole diagram of the aqueous solution of methylcellulose can be drawn. It is found that this diagram is dissymmetrical, i.e., different in shape from a circle or part of a circle; the circular form of the Cole-Cole diagram is thus not a general phenomenon, even if it is realized in many cases.
