Persistence of Relaxation and Retardation Spectra into the Glassy Zone

Persistence of Relaxation and Retardation Spectra into the Glassy Zone 

Superimposed on the background of the spectra are perceptible maxima and minima. These features are visible in curves V of Figs. 3-3 and 3-4 and can be seen more readily with an enlarged scale, revealing characteristic shapes. They can be attributed partly to very local motions of the chain backbone and partly to motions of side groups. Correlations of these loss mechanisms with structure will be discussed in Chapter 15.
