Notes:
Conductivity measurements of solutions of sodium polymethacylate (PMA), sodium carboxymethyl cellulose (CMC), and sodium alginate (AA) are presented. Measurements were made in the frequency range of 1 to 30 Mcycles/sec. The increment of electrical conductivity is taken as a measure of the dielectric loss occurring in the solution. The theories of Debye,1 Debye-Falkenhagen,2 Maxwell-Wagner,3 and the recent ionic model proposed by O'Konski4 are discussed and it is shown that the results can be satisfactorily explained only with an ionic model of the form of O'Konski's. Previous work is shown to fit in satisfactorily with this theory. In a few cases measurements of loss factors and dielectric constants are presented, and are shown to give additionnal support to the model of O'Konski.
