Dependence of dielectric properties of polymethacrylate gels in low-polarity media on degree of ionization

The dielectric dispersion of polymethacrylate gels with various degrees of ionization has been studied at frequencies $f$ of from 10 to 10$^5$ Hz. The permittivity of gels at low frequencies reached anomalously high values of 10$^7$-10$^8$ for gels swollen in methanol and 10$^4$ for dried gels, probably, as a result of the aggregation of ion pairs into multiplets with high polarizabilities. The $\lg\varepsilon'(f)$ curves of dried gels contained vertical shift regions evidencing the existence of ionic aggregates primarily of the same size. The ions in swollen gels occurred predominantly by ionic drift no matter what the degree of gel ionization. In dried gels, the character of ions transport changed from predominantly diffusion transport to ionic drift as the degree of ionization increased, probably, which testifies to a decrease in the distance between multiplets.
