摘要：
Sorption properties of porous copolymers 1-vinyl-2-pyrrolidone-divinylbenzene (VP-DVB) were investigated by thermogravimetry. Water, n-butanol and n-heptane were used as sorptives. The current studies were performed for VP-DVB copolymers which were synthesized under different condition and vary in terms of porous structure. Additionally, VP-DVB 5 sample has more polar character comparing with other samples. It was demonstrated that porous structure of the adsorbent has the fundamental impact on the adsorption process but not only the value of specific surface area but also the pore diameter plays important role. Sorption of water is enhanced by the presence of micropores and polar character of the adsorbent.
