摘要：

The distribution function of the energy of adsorption (heterogeneity function, chi) was studied for porous polymers using inverse gas chromatography. The heterogeneity functions to-wards n-hexane, n-butanol, and ethyl acetate probes were obtained for four porous polymers prepared by polymerization of styrene and divinylbenzene. The value of c for the polar surface depends on the choice of the test sorbate. The possibility of comparing surface heterogeneity of various porous polymers using the parameter chi was shown.
