摘要
将GMA与DVB悬浮聚合得到了初始共聚物PDG,再通过悬挂双键后交联反应制备出极性后交联树脂PDGpc,并研究了合成树脂对水杨酸的吸附性能。结果表明,后交联后,树脂的BET比表面积和孔容都显著增加,且对水杨酸拥有更高的吸附量。
Post-crosslinked polar resin PDGpc was prepared by the post -crosslinking reaction of the residual pendant double bonds from the initial copolymer , PDG, which was synthesized by using suspension polymerization of divinylbenzene with glycidyl methacrylate , and the adsorption behaviors of salicylic acid on the synthetic resins were studied from aqueous solutions.The results indicated that BET surface area and pore volume of PDGpc significantly increased after the post -crosslinked reaction , and PDGpc showed better adsorption performance for salicylic acid.
