Abstract
Specific features of the interaction of granulated polyvinyl chloride with polyethylenepolyamine were examined. It was shown that, to perform the reaction, it is necessary to make the granules porous by removing from the plastic compound the plasticizer and other additives introduced into the plastic compound when granules are formed. It was found that the reaction is to be performed in two stages: to treat the plastic compound with polyethylenepolyamine, with the subsequent ripening of the product at temperatures of 423 K and above. The modification yielded an anion exchanger with properties that compare well with AH-31 industrial anion exchanger. Tests performed at MAXAM-CHIRCHIQ JSC made it possible to recommend the anion exchanger synthesized in the study for use in industrial water treatment.
