Abstract

Kinetics and equilibrium of sorption of water and other organic liquids of different classes by
films from nylon-6 and nylon-6,6 were studied. The influence of sorption prehistory and crazing process
on swelling of polymeric films and on the sorption capacity of the polymer has been ascertained. It has
been shown that in some cases the sorption of weakly sorbing substances increased up to ten times in a
course of swelling due to additional adsorption sites generating. The last arised by swelling of the
polymer. The amount of sorption centers in one gram of polymer, the degree of their filling by sorbate
and the amount of additional adsorption sites were calculated
