We made time-resolved simultaneous measurements of dielectric relaxation and smallangle X-ray scattering(SAXS)on poly(ethylene terephthalate)(PET)in order to investigate the relationship between the α-relaxation and the structure formation during the crystallization process. We found that the α-relaxation changes to the α´-relaxation via a coexistent state of the two relaxations. The change in dynamics of α-relaxation occurs before the formation of higher-ordered structure observed by SAXS. The results suggest the existence of a precursor phenomenon in polymer crystallization, which is related to the dynamics in the amorphous phase.
