Thermally stimulated depolarization current investigation of the relaxation behavior of polymers with chlorocyclohexyl side groups

The considerable dielectric activity exhibited by acrylate polymers containing chlorocyclohexyl side groups is investigated by using both global and partial thermally stimulated depolarization current (TSDC) techniques. The critical interpretation of the spectra obtained by TSDC experiments on poly(2‐chlorocyclohexyl acrylate) (P2CCA), together with previous results related to the dynamics of 2‐chlorocyclohexyl acetate, model compound of the side group of P2CCA, seem to suggest that conformational transitions about O–Cy and CH–C*O* bonds, rather than chair to reverse chair transition in the cyclohexyl group, may be involved in the absorption exhibited by these polymers in the glassy state. Attempts are also made to link the relaxation spectra obtained by TSDC techniques with the ac dielectric spectra.
