三、大网均孔苯乙烯共聚物的应用1.大网均孔(或称等孔)离子交换树脂的制备大网均孔苯乙烯共聚物很容易进行功能基化反应制备各种基团的离子交换树脂。甚至交联剂含量很高的共聚物,在温和条件下通过磺化反应也可引入磺酸基。M. P. Tsyurupa等采用CMDP、XDC作交联剂制得不同交联度的磺酸阳离子交换树脂,并与DVB交联的树脂作了对比,结果见5~([18])。
Third, the big net are homogeneous styrene copolymer application 1. Large net are hole (or isopore) ion exchange resin preparation Large net homogeneous hole styrene copolymer is easy to functionalize the reaction of various groups Ion exchange resin. Even copolymers with high levels of cross-linking agents can also be introduced into sulfonic acid groups by sulfonation under mild conditions. M. P. Tsyurupa et al. Used CMDP and XDC as cross-linking agents to prepare sulfonic acid cation exchange resins with different degrees of cross-linking and were compared with DVB cross-linked resins. The results are shown in [5] and [18].
