Paper Abstract

The dielectric (alpha) relaxation occurring during isothermal crystallization of a glassy polymer PEKK has been recently measured in real time as crystallization proceeds. We use these new experimental data and the SchOnhals-Schlosser model to interpretation of the dielectric loss line shape of PEKK during crystallization. Once the crystallization proceeds, the values of the intramolecular diffusional hindrance parameter (alpha) , slightly decrease. Relatively fast, internal diffusion along polymer chain becomes a bit more hindered as a result of environmental change creates by crystallization process. Contrary, the intermolecular correlation parameter (kappa) is very sensitive to the crystallization process.
