Аннотация:Abstract—The sorption capacity of a polymeric pervaporation membrane for the target component can be
substantially increased by its preliminary treatment with a substance having an increased affinity for the poly
mer. The key features of the sorption history have calculated from balance relations. It has been found that
the flux of acetone during pervaporation through a polyamide6 membrane modified by the preliminary sorp
tion of water increased by an order of magnitude. The glasstransition temperature of the polyamide in water
has been experimentally determined to be ~50°C.
