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