以甲基丙烯酸缩水甘油酯和双甲基丙烯酸乙二醇酯作单体 ,在致孔剂存在下通过悬浮聚合将经过表面改性处理的二氧化钛超细颗粒包埋其中 ,制得一种密度增大的复合二氧化钛大孔共聚物 (GET) ,作为扩张床吸附基质 .研究了二氧化钛添加量、交联剂用量、致孔剂用量和配比对共聚物湿真密度和孔结构的影响
Using glycidyl methacrylate and ethylene glycol dimethacrylate as monomers, ultrafine titanium dioxide particles having been subjected to surface modification were embedded therein by suspension polymerization in the presence of a porogen to prepare a high density Large composite titanium dioxide macroporous copolymer (GET) was used as the matrix for the expanded bed adsorption.The effects of the amount of titanium dioxide, the amount of crosslinking agent, the amount of porogen and the ratio on the wet true density and pore structure of the copolymer
