Аннотация:A model was proposed for constructing the diagrams of compatibility of the water permeability of polymers with their physical characteristics such as van der Waals volume, density, glass transition temperature, intense thermal degradation onset temperature, and cohesion energy. A computer program that allows constructing such diagrams in automatic mode was developed. It was shown that, for polycarbonates, there exist a huge number of structures with relatively low water permeability. The choice of structures with high water permeability is significantly limited. For substituted polystyrenes the number of structures with both high and low water permeability is limited. The reason is that the repeating units of polymers of this group are synthesized from two basic fragments, while those for the rest of the polymers, from five or more basic fragments.
