In contrast to the behavior observed for the normal ferroelectric copolymer, quenching the relaxor ferroelectric terpolymer leads to a 50% decrease of the βr relaxation strength in the ε spectra at 0◦C and a concurrent reduction in ε (Fig. 15). This result supports the notion that the βr process in the terpolymer is not simply as-sociated with segmental motion in the amorphous phase, which would otherwise have led to an increase in the re-laxation strength. An earlier study by Klein et al. found that quenching P(VDF-TrFE-CFE) not only retards the crystallization process, but also induces the formation of polar all trans conformation, that is, reducing the content of relaxor nanoclusters [17].
