用苯乙烯和二乙烯苯,以水相悬浮聚合法制备多孔性聚苯乙烯凝胶时,影响其物理性能及渗透极限的因素很多,其中以稀释剂的种类及用量的影响较大。在异戊醇—二乙苯稀释体系中,找出了这两种稀释剂量的比值与渗透极限及其他物理性能之间的关系。根据这个规律,只要改变两种稀释剂的比例,就可以制备出所需孔径的凝胶。 When styrene and divinylbenzene are used to prepare porous polystyrene gels by aqueous suspension polymerization, there are many factors that affect their physical properties and infiltration limit. Among them, the type and amount of diluent are the most important factors. In the isoamyl alcohol-diethylbenzene dilution system, the relationship between the ratio of these two diluent dosings to the infiltration limit and other physical properties was found. According to this rule, the gel of the desired pore size can be prepared by changing the ratio of the two diluents.
