  • The first-order structure of a polymer is an ideally perfect long molecule chain; electrons and ions in it make contribution to the fast polarization effect. The topological deformation of the long chain gives second-order structure, and the third-order structure consists of many deformed chains; both second and third-order structures of a polymer make contribution to the slow polarization. The frozen time domain dielectric spectroscopy method shows that in β transition of a polymer, the second- and thire-order structures will be softened but the first-order one does not change. Using this method, the slow and fast components of frozen polarizations in polymer can be kept apart.
