This book focuses on the characterization of the amorphous phase of polymers whether they are
pure amorphous or semi-crystalline ones above Tg or below Tg by studying the relaxation of
dipoles and space charges naturally found in their structure after they have been activated by
the application of a voltage field. The experimental deconvolution of the relaxation modes
responsible for internal motion in the amorphous phase is coupled with a mathematical procedure
(Thermal-Windowing Deconvolution-TWD) that leads to the understanding of their coupling
characteristics which it is shown relate to the state of the material itself for instance
its non-equilibrium state or its internal stress for matter belonging to interfaces between
aggregated or dispersed phases. Describes quantitatively the Thermal Stimulated Depolarization
techniques of polymer characterization (TSD TWD) i.e. how to decouple the relaxation modes
collectively interacting (interactive coupling) and relate it to the thermodynamic properties
of the amorphous phase. Understands the results of depolarization in terms of the new physics
of polymer interactions: the Dual-Phase model here applied to the dipoles-space charge
dynamics. Provides a roaster of CASE STUDIES: practical applications of the TSD and TWD
characterization techniques to describe coupled molecular motions in resins medical tissues
wood blends and block copolymers interfaces rubbers can coatings internal stress in molded
parts etc
