Abstract

The paper presents studies devoted to the study of the heat capacity of propylene homopolymers and propylene–ethylene copolymers, comparison of the data obtained with the composition of macromolecules and the molecular weight of polymers. The paper considers the influence of the molecular weight and ethylene groups on the specific heat capacities of polypropylenes, found by differential scanning calorimetry.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
