Kolupaev B. Influence of structural elements on the energy dissipation in heterogeneous polymer systems based on polyvinyl chloride and polyvinyl butyral

The object of study. The processes of structure and regularities of formation of the influence of structural elements on the energy dissipation in heterogeneous polymer systems. Aim of the study was to establish patterns of influence of structural elements on the energy dissipation in heterogeneous polymer systems based on PVC and PVB. Theoretical and practical results. A model of energy dissipation of ultrasonic waves in amorphous polymers, which establishes the relationship between the dynamic properties of HPS and the natural frequency oscillations of the structural elements of HPS. The possibility of the change in viscoelastic properties of HPS due to inter-and intramolecular interactions, active centers of the surface topology and phase fine-fillers, energy beta radiation. The results enable the development of HPS with a controlled set of dynamic properties, including transformers and sinks of energy of acoustic oscillations, delay lines, as well as radiation-resistant materials.
