A method of producing nanodispersed systems, stabilized by the solvation mechanism, which consists of carrying out the emulsion polymerization with surface-active monomers – alkyletoksimaleinata, is developed. The influence of temperature, the ratio of monomers, the hydrocarbon radical length and number of ethoxy functional groups on the rate of the process of obtaining nanodispersions is analyzed. The study of the properties of synthesized nanodispersed systems and aggregate storage stability showed that all indicators are within certain State Standards. The spectrophotometric analysis of nanodispersions showed that emulsion polymerization occurred in all cases. Kinetics of decomposition of the initiator in aqueous solutions in the presence of surface-active monomer showed that alkyletoksimaleinata activates the stage of initiation of obtaining nanodispersed systems. Alkyletoksimaleinata proved to be more effective than widely used in emulsion polymerization the emulsifier OP-10. It is established that nanodispersed systems are stable during storage. The use of nanodispersed systems, modified by surface-active monomers, makes it possible to exclude the stage of plasticization by low-molecular compounds that degrade the electrical properties of the product. This leads to a reduction in the material and energy costs, to an increase in the life of the product, since in this case there is no exudation of the plasticizer, which worsens the quality of the product and causes environmental pollution. It is established that the main role in the stability of nanodispersed systems, modified by surface-active monomers, plays the hydration of particles. The technology of production of modified nanodispersed systems based on vinyl acetate and surface-active monomer is developed. The technological scheme of production of modified nanodispersed systems is arranged, the binding of the main apparatus is made. Rational use of raw materials will allow to obtain a higher yield of the product. The nanodispersed systems, modified by surface-active monomers, can be used in all areas where systems with conventional emulsifiers are used.
