FIELD: polymer materials.
SUBSTANCE: coating comprises selectively permeable layer and contains polyamino polymer wherein at least 10% amino groups of polymer are amino acid groups having pKA values of acid moieties below 6.4. Layer is characterized by water vapor passage velocity at least 2000 g/m2·day and permeability for bis-2-choroethyl sulfide 0.02 cm/sec or less at relative humidity 80%. Coating can be used for creating protective working clothes and accessories.
EFFECT: allowed passage of higher amounts of water and substantially limited passage of harmful and dangerous chemicals.
