It is shown that, in a neutral media, zinc ions form complexes with polyhexamethylene guanidine derivatives as a result of which the adsorption of oligomers on different interfaces is intensified. The increase in the adsorbability of complexes is connected with the increase in the hydrophobicity of macroparticles and with the intensification of their displacement by the solvent onto the interface, which promotes an additional decrease in the corrosion rate of the metal as compared with base oligomers.
