摘要：

Porous polymeric sorbents showing selective CO2 absorption over N-2 are prepared by conventional radical copolymerization of divinylbenzene and 4-vinylbenzyl chloride under solvothermal conditions, followed by surface modification of the pores with polyamines. The amine-functionalized porous materials that interact with CO2 via chemisorption exhibit exceptionally high CO2/N-2 selectivity of up to 373 times, determined by ideal adsorbed solution theory (IAST).
