Abstract
A soluble polymer with intrinsic microporosity, 2,4-diamino-1,3,5-triazinefunctionalized organic polymer, is used for the first time as a solid adsorbent, providing an easy solution to overcome the fouling issue. Promising adsorption performances including good CO2 adsorption capacity, excellent CO2/N-2 and CO2/CH4 selectivities, high chemical and thermal stabilities, and easiness of preparation and regeneration are shown.
