摘　　要：以丙烯酸甲酯和二乙烯基苯悬浮共聚,制备了交联度分别为5%、7%、9%的大孔交联聚丙烯酸甲酯(PMA),通过与二乙烯三胺的胺解反应得到了大孔交联聚丙烯酰二乙烯三胺(PAM)吸附树脂;通过红外光谱(FT-IR)对树脂的结构进行了表征;系统考察了静态吸附法下PAM树脂对CO2的吸附性能以及作为CO2吸附材料的循环使用性能。结果表明,在室温下交联度为5%的PAM树脂具有较高的CO2吸附量,达143.1 mg/g吸附剂,CO2吸附量随胺基数量增加而增大,且PAM树脂具有良好的循环使用稳定性。Macroporous polymethylacrylate （PMA） with three different crosstinking degrees i.e. 5 % , 7 % , 9 % , was synthesized by the conventional suspension polymerization of methylacrylate and divinylbenzene. Spherical maeroporous N-substituted polyacrylamide adsorption resin （PAM） was prepared via the aminolysis reaction of PMA with diethylenetriamine. The resins were characterized by FT-IR. The CO2 adsorption capacity, adsorption ra＇te and cyclic capacity under static adsorption condition were investigated. The results show that when the crosslinking degree is 5 % , the adsorbent has a much higher adsorption capacity of 143.1 mg CO2/g at room temperature. With the amine number increaseing, CO2 adsorption capacity also increases. This adsorbent has the good cyclic using stability.
