高度交联聚苯乙烯吸附剂的结构与吸附性能研究

在通过Ｆｒｉｅｄｅｌ—Ｃｒａｆｔｓ后交联反应制备高度交联聚苯乙烯吸附剂的过程中，向反应体系中加入非极性芳香化合物甲苯，当加入少量甲苯时，吸附剂的比表面积、孔容等变小，但其吸附能力却明显提高；当加入甲苯超过某一量时，其吸附能力又随加入甲苯的量的增加而降低，这说明孔结构和骨架结构共同影响着高度交联聚苯乙烯吸附剂的吸附性能．

大孔交联聚苯乙烯分形结构的图像分析法研究

采用图像分析法测定大孔交联聚苯乙烯树脂的 现大孔交联聚苯乙烯的外表面具有分形结构,分形维数在２和３之间,将图像分析法测定的分形维数与小角Ｘ－射线散射法测得的结果对照。发现两种方法测定结果虽然不同,但在不同树脂之间的变化趋势是一致的,因此,可用图像分析法比较不同大孔树脂分形结构的差别。     

CHLOROMETHYLATION OF POLYMERS MADE FROM TECHNICAL DIVINYLBENZENE AND PROPERTY OF THE CHLOROMETHYLATED POLYMERS

The goal this paper was to reveal the feasibility of chloromethylation of polymers made from technical divinylbenzene so as to introduce functional groups into polymeric adsorbents.Forthis study,the factors,that effect the chloromethylation reaction,such as the pore structure of the polymer,the ratio of the reactants to catalyst,the reaction temperature and reaction time and so on were investigated.and the pore structure and property of the chloromethylated polymers were studied.The results showed that polymers of technical divinylbenzene could be chloromethylated successfully,and the adsorptive property of the chloromethylated resin was different from that of the initial resin.     

MOLECULAR IMPRINTED POLYMERS—Novel Polymer Adsorbents

Molecular imprinted polymers(MIPs) are novel functional polymer materials and known as specific adsorbents for the template molecules,These novel functional polymers have promised potential applications in racemic resolution,sensor,chromatography,adsorptive separation and other fields.This review exhibits the approach for preparing MIPs,the features of MIPs obtained by different routes and the characteristics of adsorptive separations with MIPs.The molecular recognition mechanism and the idea of the present possibilities and limitations of molecular imprinting polymerization are discussed as well.     

ADSORPTION OF PHENOL IN NON-AQUEOUS SYSTEM BASED ON HYDROGEN-BONDING

1 INTRODUCTIONHydrogen-bonding adsorbents are functional polymers for adsorption and separation via theformation of hydrogen bond between the adsorbentS and adsorbates. Because hydrogen bond is astrong intermolecular (or intramolecular) force, hydrogen-bonding adsorbents have strong potentto adsorbing adsorbates with which can form hydrogen bond. In our previous work, three seriesof hydrogen-bonding adsorbents have been studied, which were adsorbents with hydrogendonator, adsorbentS with …
