The relaxation mechanisms present in a side-chain liquid crystalline polymer have been studied by Thermally Stimulated Depolarization Currents (t.s.d.c.), in a wide temperature range covering the glassy state, the glass transition region, and the liquid crystalline phase.

## Abstract In the present work we report the results of a Thermally Stimulated Discharge Currents (TSDC) study of a side‐chain liquid‐crystalline polymer. The different discharges observed in the TSDC spectrum have been analysed by the thermal sampling technique and have been attributed to specifi

## Abstract Thermal relaxation behavior of a mechanically induced macroscopic orientation of the mesogenic groups in a side‐chain liquid crystalline polyacrylate was investigated using timedependent polarized infrared spectroscopy. It was found that a complete relaxation occurred only at temperatur
