Jjm. Ramos et Jf. Mano, DIPOLAR RELAXATIONS IN A SIDE-CHAIN POLYACRYLATE LIQUID-CRYSTAL - A STUDY BY THERMALLY STIMULATED CURRENTS, Thermochimica acta, 285(2), 1996, pp. 347-359
The dipolar relaxation mechanisms present in a side-chain liquid cryst
alline polyacrylate were studied in a wide temperature range covering
the glassy state, the glass transition region and the liquid crystalli
ne phase. The complex relaxation processes observed in these different
temperature regions were analysed in detail using the technique of th
ermal cleaning. The significance of the so-called compensation behavio
ur, which is frequently considered as a feature of the glass transitio
n relaxation in polymeric materials, is discussed.
