Аннотация: Diagrams of compatibility of water permeability with glass transition temperature,density, and cohesion energy are constructed. The computer program "Cascade", INEOS RAS was used. Polyolefins, vinyl polymers, and polycarbonates were analyzed. Compatibility diagrams are constructed for the areas of lowest and highest water permeability for different classes of polymers. For polyolefins and vinyl polymers, the lowest water permeability is selected in the range from 0 to 100 barrer, and the highest water permeability is from 1000 to 2000 barrer. For polycarbonates, the intervals from 0 to 70 barrer and from 3000 to 7000 barrer are selected. These diagrams allow you to select polymers that meet the specified values ofdensity, cohesion energy, glass transition temperature, and the onset of temperature of intense thermal degradation.
