Dielectric relaxational behavior of poly(monochlorobenzyl methacrylate)s (PMClBM) and poly(dichlorobenzyl methacrylate)s (PDClBM) has been analyzed. The study was carried out by determining the components of the complex dielectric permittivity ε*. Two relaxation processes, labelled as α and β relaxations, which were analyzed in terms of the Havriliak-Negami and Cole-Cole equations, respectively, have been experimentally observed. The relative position of the chlorine substitute in the benzyl ring determines the characteristic parameters of the relaxations. Complementary dynamic mechanical measurements on these polymers have been carried out. The relationship between the macroscopic measurements with the dipolar moment of the relaxing entities has been analyzed in terms of the Onsager-Kirkwood-Frohlich equation. |
