The present account summarizes briefly selected aspects of earlier DRS studies of polymers and of recent development, especially those concerning short- and long-range motions of chains and systems undergoing polymerization. [Pg.276]

The phenomenological theory of the dielectric relaxation behaviour of linear systems is well-established [1-5]. The fundamental relationship joining the frequency-dependent complex permittivity c(cu) measured at frequency / = (ofln and the transient step-response function t) is the Fourier transform relationship [Pg.276]

if an increase in pressure decreases the strength of the fi process, then there will be a consequent increase in the strength of the a process in order to conserve Ac, as we and others have observed [12,17,20]. [Pg.277]
