摘要：本文研究了二甲氨基乙基醚为离子交换单元的强阴离子交换亲水性聚合物的可控制备。实验中，通过以甲基丙烯酸乙酯作为聚合物化学反应的原料，在不同pH条件下选择不同量的盐形式及量加入到原料中，并加入一定量的聚合物促进剂、固化剂、表面活性剂，使用水作为反应介质进行反应。最后得到一系列不同盐形式、浓度和pH条件下所得到的聚合物样品。实验表明：随着所选盐形式、浓度和pH条件的不断变化，所得样品具有不同的性能。在正常情况下（盐形式是NaClO4,浓度是0.25mol/L,pH=7.5~8.5)时所得样品具有优异的性能；该聚合物对正电荷有优异的交换能力;该材料也显示出优异的耐久性并拥有低成本、易处理性。因此,该工作对于理论上对多金属-氮-氯-氰三价金属单元(MNC)耦合超分子体系(CMS) 研究愿意大大地促进我们对MNC CMS 系统理论上方法学上方法学上方法学上方法学上方法学上方法学上方法学 和 实骅 研 究把 控 。 Introduction: Ion exchange materials have been widely used in many fields such as water treatment, food processing and biomedicine due to their excellent properties. In recent years, the development of ion exchange materials has become more and more extensive. Among them, strong cationic ion exchange hydrophilic polymers with dimethyl ethyl ether (DMEE) as the ion exchange unit has attracted much attention due to its excellent performance and controllable preparation process. It is a kind of material with high selectivity for positive ions and good resistance to acid and alkali corrosion. Therefore, it has great potential application value in various fields such as water purification and food processing. Experimental: In this experiment, methyl acrylate was used as the raw material of polymerization reaction. Different amounts of salt forms and concentrations were added into the raw materials under different pH conditions, and a certain amount of polymerization catalyst, crosslinking agent and surfactant were added to use water as the reaction medium for reaction. Finally a series of polymer samples obtained under different salt forms concentration and pH conditions were obtained. The experimental results showed that with the continuous change of selected salt forms concentration and pH conditions ,the obtained samples had different performances .Under normal conditions (salt form is NaClO4 ,concentration is 0 .25mol/L , pH=7 .5~8 .5 )the obtained samples had excellent performance ;the polymer had excellent exchange capacity for positive charges ;the material also showed excellent durability And low cost easy processing . Conclusion: The study on controllable preparation of strong cationic ion exchange hydrophilic polymers with dimethyl ethyl ether (DMEE) as ion exchange units has been completed successfully in this paper .It can be seen from the experimental results that under normal conditions ,the prepared sample has excellent performance ,which can be used in various applications such as water purification or food processing .Therefore ,this work will greatly promote our theoretical research on multimetal-nitrogen-chlorine-cyanide trivalent metal unit (MNC )coupled supramolecular system (CMS )and control experimentally research on MNC CMS systems
