苯乙烯(S)、二乙烯本(DVB)、双(α-甲基丙烯酸)乙二醇酯(EGDM)共聚物是在200~#汽油存在下,通过悬浮聚合制备的,其中DVB和EGDM混合物作为交联剂。实验结果表明,共聚物的比表面积是随交联剂和稀释剂的用量而变化的。采用汽油和甲苯混合致孔剂共聚物的孔和表面结构得到改进,采用不同后处理所得共聚物的比表面积不同。这种聚合物吸附剂对间接胆红素和B_(12)吸附性能较好。 Styrene (S), divinylbenzene (DVB), ethylene glycol dimethacrylate (EGDM) copolymers were prepared by suspension polymerization in the presence of 200 ~ # gasoline with a mixture of DVB and EGDM As a crosslinking agent. The experimental results show that the specific surface area of ​​the copolymer varies with the amount of crosslinking agent and diluent. The hole and surface structure of the copolymer using gasoline and toluene mixed porogen is improved, and the copolymers obtained by using different post-treatments have different specific surface areas. This polymer adsorbent has good adsorption capacity for indirect bilirubin and B_ (12).
