Novel polyurethanes, polyamidourethanes and polyurethane foams of stable to biocorrosion were synthesized. The polymers possess fungicidal/fungistatic and bactericidal/bacteriostatic activity. After the biological tests with using of mold fungi and yeasts, polymers totally keep their main exploitation characteristics: for most of polymers coefficients of strength and elasticity keeping are equal of 100%. Most of them possess the fungicidal properties of zero balls, according to the State Standard. Life-firmness investigation of the most aggressive extremophiles: mold fungi Penicillium and Aspergillus on the polymer surfaces showed that for some samples it made up from 3 to 10 days. Some polymers possess both anti-micotic and anti-bacterial action. Based on investigation results a special technological scheme of assured human protection against microorganisms attack in specific condition of his existence are to be elaborated.
