ABSTRACT A methodology of using chloroacetylated polystyrene resin (PS‐COCH 2 ‐Cl) to initiate the ring‐opening polymerization oxazolines was established prepare highly amininated (PS) beads for CO adsorption. The structure resulting material fully characterized by FTIR, BET, TGA, and XPS, results suggested that chloroacetyl group more reactive in initiating than known chloromethyl groups, which eliminated use iodide salts are costly. could adsorb at an equilibrium adsorption capacity 3.15 mmol/g 25°C 1 atm, isotherms conformed Freundlich isothermal model, indicating a multi‐layer type. Kinetic study predominantly governed chemical interactions with physical playing supportive role. For simulated flue gas 15% /N , 50°C, relative humidity 80%, SO concentration 50 ppm, performance PS‐COCH ‐LPEI even improved can be well retained least 20 adsorption–desorption cycles, demonstrating promising application prospect this solid polyamine removing from gas.
