Abstract: The technology for producing new composite materials based on industrial multi-tonnage polymers polyethylene (PE), polyvinyl chloride (PVC), polyurethane thermoelastoplast (DUTEP), butyl rubber (BC), chlorocarboxylate polyethylene (HCPE), ethylene propylene rubber (SKEP) has been developed. Determined thermodynamic relationship (compatibility) system-butyl rubber-polyethylene (BK-LDPE), polyvinyl chloride, high – pressure polyurethane thermoplastic (PVC-UTEP), PVC chargeability polyethylene (PVC-CPE), HCPE of UTEP, BC-GATED (EPDM material-VC) by the method of inverse gas chromatography and identified structural features of these systems using IR spectroscopy and polarizing microscopy. It is shown that the presence of polyfunctional groups (chlorine, hydroxyl, carboxyl) significantly affects the compatibility mechanism and gives a universal set of properties (increased adhesive strength, tear and tear strength, resistance to thermal and chemical The solubility parameters of four polymers of different polarities were determined using turbid metric titration (TD) and reverse gas chromatography. Based on the temperature dependence of the solubility parameter obtained from the retention times of the sorbents, the solubility parameter value was calculated, reduced to 298 K, and compared with the value obtained by the TDG method at the same temperature. An increase in the difference between the values of the solubility parameters obtained by the two methods is shown with an increase in the polarity of the polymer. The observed effect is explained by the Diametrically opposite state of the studied polymer-solvent systems
