Abstract :
The aim of the present work is to give a contribution to the discussion of the nature, at the molecular level, of the relaxations above Tg observed in the TSDC studies of side-chain liquid crystalline polymers and, at the same time, to try to establish some kind of correspondence between those relaxations and the δ and α peaks observed by dielectric relaxation spectroscopy
