该项研究发现了大孔交联聚苯乙烯型离子交换树脂的合成方法,研究了惰性溶剂的性质与树脂的孔结构、树脂的孔结构与树脂的性能、树脂的特性与用途等方面的关系。在此基础上,研制出高强度、抗辐射、动力学性能优越的大孔型离子交换树脂,使其不仅能更好地应用于无机离子的交换,还开拓了在有机合成、制药等领域的催化、脱色、提纯等多方面的广泛应用。在多孔性离子交换树脂的基础上,还研制出系列吸附树脂。此类提取、分离材料,可以有不同的结构和不同的吸附性能,在天然产物的提取分离、抗菌素的提取、纯化、医疗、环境保护等领域有实际用途。上述两类功能高分子材料在多家企业实现了产业化,为化工、制药、环保、医疗、分析等诸多行业提供了必要的材料,在国民经济的发展中发挥了重要作用。

In the studies of this item, the paper contains three parts： the first part was the discovery of the synthesis of polystyrene macroporous ion exchange resins; the second part was to study the preparation of the macroporous resins in the presence of inert solvent of different properties; the third part was the investigation of the relationship between the structures and the properties. Based on the studies, it was proved that the properties of the macroporous resins possessed radioresistance, good ion exchange reaction kinetics and excellent mechanical strength. The macroporous ion exchange resins were not only exchanging very well with the inorganic ions, but also could be used for decolorization, catalyst and purification of organic substances. The macroporous resins without functional groups could be used as polymeric adsorbents. They can be used for the extraction and purification of natural products and also be used for antibiotics production, blood hemoperfution, environmental protection, etc. The macroporous ion exchange resins and adsorbents mentioned above have been produced and widely applied in chemical industry, medicine production, environmental protection, medical treatment, analysis and so on.
