Abstract. The mechanisms of formation of the structure of polymer blends with different thermodynamic compatibility of components are considered. A synergistic effect was obtained to increase the parameters of performance characteristics and resistance to thermal-oxidative degradation during the formation of products and functional coatings from industrial polymer blends through the use of plasticizers that increase the segmental mobility of macromolecules in the temperature range of formation of the product and coating, and low-dimensional (including nano-sized) particles of various compositions , structure and production technology, acting as a physical compatibilizer. Nanocomposite materials based on thermoplastics blends have been developed for the manufacture of products and coatings used in the construction of automobile components, technological tool, belt conveyor, fastening elements, elements of road and construction structures.

Keywords: polymer blends, composite material, composite structure, physical compatibilizer, functional coating.

Introduction. Modern mechanical engineering is characterized by an increase in the proportion of functional materials based on industrially produced polymeric and oligomeric binders due to the developed technologies for modifying their structure in order to achieve optimal parameters of stressstrain, tribological, adhesive, etc. characteristics and effective methods of their production and processing into products [1].
Currently, there are a number of effective directions for managing the parameters of the structural characteristics of industrial binders by introducing functional fillers and components into their composition that affect the mechanisms of formation of supramolecular structures, the mechanisms of intermolecular interaction, the kinetics of the course of thermo-oxidative and destructive processes, etc. in the static and dynamic interaction of products made of functional materials with a metal coupled element [1, 2]. At the same time, the development of machine-building production, the improvement of the service system of operated equipment, increased attention to the impact of polymer composites in their production, processing into products and their operation on environmental components put forward new tasks to improve the technology of functional materials based on polymer and oligomeric matrices.
In the applied areas of mechanical engineering, a special place is occupied by composite materials based on blends of industrially produced materials, which have a developed base for their production and processing, which significantly reduces the cost of manufacturing and operating functional products.
The purpose of this work was to study the main directions of formation of functional materials with high performance characteristics based on industrially produced thermoplastics.
