摘要：

The molecular relaxation of polychloroprene has been studied at temperatures in the melting range. The melting of the crystalline structure corresponds to the maxima of the dielectric losses and permittivity. The change in the dielectric relaxation parameters is related to a difference in the liquid properties between sections of macromolecules in the intercrystal layer, the sections being gripped in the crystallites, macromolecules in the amorphous regions and those in the amorphorous elastomer.
