Еo develop the physico-chemical and technological bases of the technology of obtaining and applying polymer-composite coatings based on modified polymer and reactive oligomeric adhesives, suitable for use as multi-purpose coatings (protective against of electromagnetic radiation, masking from radar surveillance, antistatic and anticorrosive) with adjustable conductivity, ability to interact with electromagnetic radiation and reduced ability to ionize.

The physicochemical and technological features of the modification of polymer binders based on methyl methacrylate have been established. It has been found that the addition of modified silicates leads to a decrease in the rate and the limiting degree of polymerization. It has been established that the presence of a modified silicate filler contributes to a significant reduction in technological shrinkage. The highest hardness and heat resistance are observed for compositions containing Cu-PVP-silicate filler.
The features of the modification of oligomeric binders based on unsaturated polyester resins with plasticizers of various nature and polyvinyl chloride have been studied. It has been established that the introduction of dibutylphthalate contributes to an increase in the homogeneity of the system, increases the thermodynamic compatibility between the polymer, oligomer and styrene. The physicochemical regularities of the plasticization of the natural starch filler with epoxidized soybean oil and glycerin have been established.
The influence of the polymer modifier - polyvinylbutyral on the structuring features of epoxy resin was revealed, it was established that the introduction of the modifier contributes to the increase in the adhesive strength of the joints. Modification of epoxy materials with starch allows you to regulate the strength properties of the material - hardness, equilibrium modulus of elasticity and deformation modulus. It was established that the addition of carbon black as an active filler increases hardness, modulus of elasticity and highelasticity.
The influence of technological and physicochemical factors on the process of modifying finely dispersed carbon black with polyvinyl alcohol and polyvinylbutyral was established. The greatest efficiency of modification is observed with additional ultrasonic treatment of filler suspensions.
