Abstract
AbstractSummary: The relaxation behaviour of poly(5‐acryloxy‐5‐methyl‐2,3‐dioxacyclohexne), poly(2,3‐dichlorobenzyl methacrylate) and poly(3‐chlorobenzyl methacrylate) was thoroughly studied by broadband dielectric spectroscopy with the aim of investigating how the chemical structure affects the response of polymers to electric perturbation fields over a wide temperature window. Retardation spectra calculated from dielectric isotherms utilizing linear programming regularization parameter techniques were used to deconvolute strongly overlapped absorptions. Special attention is paid to both the splitting region and the fitting of the Williams ansatz to the experimental results. Attempts are made to explain the molecular origin of the relaxations observed in the retardation spectra of the polymers.
