Abstract:<\/strong><\/p>\nEpoxy polyurethanes (EP) modified with branched polyurethanes containing Cu-organic compounds have been prepared, which has high physical and mechanical properties. Epoxy polyurethanes\/network polyurethanes\/copper acetylacetonate (EP\/NPU70:30\/Cu(AA)2) samples are characterized by high, and improved relative to epoxy urethanes, adhesion\/cohesion properties, namely: 37.0\/42.8 MPa. They are resistant to natural aggressive factors: UV and IR radiation, as well as fungicidal properties, their fungal resistance is 0 points. It has been found that all synthesized polymers, both of the original branched polyurethanes and epoxy polyurethanes, and branched polyurethanes and epoxy polyurethanes modified with a Cu-organic compound, are resistant to water, gasoline and organic solvents. The prolonged nature of the protective properties of polymers is ensured by the reliable fixation of Cu(AA)2 in their composition, which is confirmed by the data of IR spectroscopic studies. It was found that in the process of interaction of Cu(AA)2 with toluene diisocyanate (TDI), the formation of the amide group -\u0421\u041eN\u041d- occurs as a result of the addition of the \u03b3-hydrogen of the \u0421\u041d group of Cu(AA)2 to the nitrogen of the N\u0421\u041e group of TDI (appearance of the stretching vibration at 3296 \u0441m\u22121). A change in the profile of bands (intensity and position) of stretching and deformation vibrations of \u0421-\u041d bonds of other groups of the Cu-organic compound (1451\u20131304 cm\u22121) and in the region of bending vibrations of the \u0421u-\u041e band (500\u2013750 cm\u22121) was noted. This indicates their participation in intermolecular interactions with fragments of the PU macrochain, thus contributing to the fixation of active substances in the polymer structure and, in turn, making it impossible for them to diffuse to the surface of the material with their subsequent removal, which prolongs the protective functions of the coatings.<\/em><\/p>\nKey words: <\/em><\/strong>polyurethanes, branched polyurethanes, organometallic modifiers, stability, adhesion\/cohesion, performance properties.<\/em><\/p>\nREFERENCES<\/strong>
