利用新型交联剂──双甲基丙烯酰氧苯基丙烷（双烯－Ａ）与苯乙烯悬浮共聚合，以甲苯、异戊醇作致孔剂，合成了一系列大孔高交联共聚物。考察了双烯－Ａ用量、甲苯／异戊醇配比、引发剂用量及分散剂用量对共聚物孔结构的影响，通过红外光谱、表现密度、全自动物理吸附仪及扫描电镜对干燥的共聚物小球进行了表征。结果表明，随交联利双烯－Ａ含量的增加，苯乙烯－双烯－Ａ共聚物的表面孔结构明显增大。共聚物的比表面积、孔容及孔径均随致孔剂中不良溶剂异戊醇含量的增加而明显增大。
A series of macroporous cross-linked copolyesters were synthesized by suspension copolymerization of bismethacryloyloxy-propane (diene-A) with styrene and toluene and isoamyl alcohol as porogen Things. The influences of the amount of diene-A, the ratio of toluene / isoamyl alcohol, the amount of initiator and the amount of dispersant on the pore structure of the copolymer were investigated. The effects of the copolymerization on the copolymer were investigated by infrared spectroscopy, density, automatic physical adsorption and scanning electron microscopy Material pellets were characterized. The results showed that the surface pore structure of styrene-diene-A copolymer increased obviously with the increase of the content of cross-linked DL-A. The specific surface area, pore volume and pore size of the copolymer all increased significantly with the increase of the content of isoamyl alcohol in the porogen.
