Abstract

The features of the electronic structure of Matrimid, which are important for assessing the sorption ability of the specified polymer as a membrane material, are considered. Using the density functional theory, the charge states of sorption centers in the Matrimid are calculated. The most probable polymer atoms responsible for nonvalent interactions of polar molecules of gases or liquids when passing through membranes based on this polymer are investigated.
