RELAXATION SPECTROMETRY OF AMORPHOUS POLY MERS - A NEW METHODOLOGY AND A NEW METHOD

A new methodological approach is proposed for studying the relaxation process in an amorphous polymer. On this basis, a correction is sugges ted in the graphical-analytical method of determination of the preexpo nential factor in the Arrhenius-Boltzmann law for the relaxation time. A correlation is found between the spatial, temporal, and energy spec tra of the supermolecular organization of a polymer. The effect of mut ual compensation of the preexponential factors and activation energies is experimentally established for the basic Arrhenius-Boltzmann equat ion describing the relaxation time in an amorphous polyimide.
