一种丙烯酸系强碱阴树脂的研制——聚丙烯酸甲酯胺解反应的研究

On the Development of A Strong Base Anion Exchange Resin of Acrylic Acid ——Aminolysis Reaction of Polymethyl Acrylate

交联的聚丙烯酸甲酯在甲苯的存在下与二乙烯三胺反应 ,其胺解率高 ,则经季胺化后制得的大孔丙烯酸强碱阴树脂的性能越好。本文讨论以混合致孔剂的不同比例制得不同的白球 ,并在胺化反应时采取多种措施 ,使所得的胺球重量交换量稳定在 8 5mmol/g ,最高值为8 9mmol/g。

With the existence of toluene,cross linked polymethyl acrylate can react with divinyl triamine,the higher the aminolysis rate is,the better the function of macropore strong base anion exchange resin of acrylic acid from quaterisation will be. The present paper makes a discussion of different white ball produced by distinct proportion of mixed perforating mixture with proper adjustment of the proportion in the process of the reaction of amination,which is supposed to keep the weight of the exchange capacity of amine’s ball at 8 5mmol/g,while the highest value is 8 9mmol/g.
