Abstract: Sulfonic cation exchangers were obtained using a simplified technology: sulfonation of the finished polymer framework, i.e. polymer composition based on wastes of polystyrene mechano-chemically modified with polyvinyl chloride and study of the properties of synthesized cation exchangers. As a result of the research, a mechano-chemical modification of polystyrene waste with polyvinyl chloride was carried out. The modification process was carried out over a wide range of temperatures, time and shear stress by capillary viscometry. The modified systems are sulfonated with concentrated sulfuric acid in the presence of anhydrous ?AlCl? _3 as a catalyst, and ion-exchange materials have been obtained. Were studied such properties of sulfonic cation exchangers as static and dynamic exchange capacity, mechanical strength, swelling coefficient. It is shown that sulfonic cation exchangers obtained on the basis of the mechanochemically modified system OPS: PVC are not inferior in their main indicators to the industrial sulfonic cation exchanger KU-2. We propose the use of synthesized sulfonic cation exchangers for water demineralization.
Key words: olystyrene, modification, sulfocationate, mexono-chemical modification, ion-exchange material, polymer composition, polymer solubility index, sulfuric acid.
