The article deals with the synthesis reaction to produce and interact with dialkylaminoalkyl halogen-containing substances, their composition and structure was studied by elemental, IR, PMR-spectroscopic analyzes. Electrocapillary studied curves, the electric charge density, the concentration of adsorbed molecules, the dependence of the differential capacitance of the synthesized substances. The results of the studies showed that the synthesized crystalline quaternary ammonium salt with dialkylaminoalkyl methacrylate-based materials have the properties of halogen-containing surfactant, cation type.
