The characteristics of molecular motion of the vinylidene fluoride (73)/trifluoro ethylene (27) copolymer ferroelectric have been investigated by dielectric relaxation measure-ments at low temperatures and low frequencies.With increase of the crystallinity of the copolymer,the Curie-point temperature T_c decreased and the dielectric constant increased in the region of ferroelectric-paraelectric phase transition.The frequency spectra of the copoly-mers below room temperature consisted of a low-frequency part ascribed to the micro-Brownian motion of molecular segments in the noncrystalline regions and a high-frequency part designated as the local motions of small-scale segments.The T_g (=-37℃) and △H (=48.8kJ/mol) of copolymers were obtained from the fitted results using two Cole-Cole functions andcalculation with WLF equation and Arrhenius formula respectively.
