- Аннотация: The possibility of using organomineral complexes of polyhexamethylene guanidine hydrochlorideas a functional additive for a waterborne paint based on polyvinyl acetate has been investigated. Organomin-eral complexes containing 20 and 30 wt % guanidine polymer have been obtained, with intercalation ofpolyguanidine chains into the interlayer space of montmorillonite being observed. It has been revealed thatthe stability of the polymer film to water is retained when organomineral complexes are introduced into apolyvinyl acetate dispersion, whereas the water resistance of the film sharply decreases when free polyguani-dine is added. There was no significant influence of organomineral complexes on the rheological character-istics of the dispersion and its sedimentation stability. Testing of waterborne paints with various additives hasshown that introduction of organomineral complexes into the material prevents the coating from fouling bybiofilms of gram-positive bacteria Staphylococcus aureus and Rhodococcus erythropolis, with the hardness,water resistance, and water-vapor transmission of the coatings being retained at a satisfactory level.
