Abstract:<\/p>\n

New <\/em>cross<\/em>–<\/em>linked<\/em> and linear polyurethane compositions with different content of <\/em>various<\/em> reactive metal[<\/em>Ni<\/em>,<\/em>Zn<\/em>,<\/em>Cu<\/em>]inorganic modifiers (M<\/em>IM<\/em>) were synthesized. The results of <\/em>IR<\/em> spectroscopy confirm the reaction and structural reorganization in the system under the influence of M<\/em>I<\/em>M.<\/em> Thus, in the region of stretching vibrations of NH groups of the urethane fragment, a shoulder <\/em>increase <\/em>was noted in the region of weakly bound stretching vibrations of NH groups at 3456 cm-1<\/sup> and a new band at 4314 cm-1<\/sup> appears, which indicates the presence of hydrogen bonds with the chlorine ion CuCl2<\/sub>.<\/em> The presence of M<\/em>I<\/em>M in polyurethane leads to a shift of valence <\/em>vibration of <\/em>urethane group band <\/em>\u03bd\u0421<\/em> =<\/em>O to<\/em> the region of 1723 cm-1<\/sup> and the appearance of an intensive shoulder 1711 cm-1<\/sup>, which indicates the formation of a coordination bond C = O<\/em> \u2192 <\/em>Cu[Cl2<\/sub>]<\/em>.<\/em> T<\/em>he appearance in the IR spectrum of the polymer with MENM content of three new bands with maximums (530, 558 and 637) cm<\/em>–<\/sup><\/em>1<\/sup><\/em> indicates the formation of a coordination bond N \u2192 Cu.<\/em> It <\/em>was<\/em> shown that the presence of transition metals dichloride<\/em>s<\/em> in the polymer structure provides opportunities for <\/em>target<\/em> production of polyurethane compositions with a set of specified properties, namely: fungicide properties<\/em>,<\/em> which were <\/em>provide<\/em>d by<\/em> the presence of Zn- and Cu-chlorides, photostability <\/em>which was <\/em>provide<\/em>d<\/em> by<\/em> the presence of Ni-chloride.<\/em> In this case, the incorporation of active compounds into the structure of the polymer excludes the diffusion of MIM on the surface of the material with subsequent removal and thus prolongs the protective functions of the coating – resistance to biocorrosion, UV radiation, chemical agents, heat resistance while maintaining high adhesion \/ cohesion.<\/em><\/p>\n
