Abstract
Some of the main working principles in behavior characterization of polymer systems deduced in topoenergetic terms are applied for three thermally driven transformation processes specific to macromolecular systems, namely: thermal oxidation of amorphous phase in high and low density polyethylenes blended with carbon black, crystallization from the melt and the the melt and the ductile‐to‐brittle transition as a result of amorphous morphology annealing. The two parameters determined according to the kinetic equcations, univocally define the system behavior in the considered energetic circuits, and physically correspond to establishing the relative indentity of the process and its relative amplitude.
