Description
Summary:Obtaining and using polymeric composite materials with biocide properties is of considerable practical interest both for making construction materials stable against biological corrosion and for improving the sanitary-epidemiological situation. The method suggested for obtaining biocide polymeric composites is based on using new guanine-containing polymers immobilized on montmorillonite as biocide additives. Macromolecular compounds based on guanidine polymers are characterized by high biocide efficiency and low toxicity, and their use as organomineral complexes with montmorillonite can rule out washing-out of the additive from the composite and improve the distribution of the additive in the composite. Methods are suggested for obtaining organomineral complexes in a wide range of compositions. It is shown that composites based on polyethylene and the additives have high biocide efficiency toward micromycetes and gram-positive and gram-negative bacteria.
