采用化学接枝的方法,合成多孔性高强度的强碱性和强酸性离子交換剂,预料可以用相似的技术合成其他类型的多孔性高强度离子交换树脂。在共聚合反应,氯甲基化反应及銨化反应中做了些生产数据,可投入生产。性能測定結果証明:新型树脂具备良好的交換量,迅速的交換速度(它与3,5-二硝基苯甲酸的二級反应速度常数約比E.Merck的大4.5—4.9倍),高的含水量,低的溶胀度;在显微镜下观察沒有裂痕,其耐压程度較Amberlite 1RA-400,401,Dowex-1(或Nalcite SBR)等树脂高2—3倍以至6—7倍。
The use of chemical grafting methods to synthesize porous, high strength, strongly basic and strongly acidic ion exchangers is expected to synthesize other types of porous, high strength ion exchange resins using similar techniques. In the copolymerization, chloromethylation reaction and ammonium reaction done some production data, can be put into production. Performance measurement results show that: The new resin has good exchange capacity, rapid exchange rate (which 3,5-dinitrobenzoate with 3,5-dinitrobenzoate reaction rate constant is about 4.5-4.9 times larger than E. Merck), high Water content and low swelling degree. No cracks were observed under the microscope. The pressure resistance was 2-3 times as high as that of resins such as Amberlite 1RA-400,401, Dowex-1 (or Nalcite SBR), and even 6-7 times.
