With connection to the previous papers, we inform here the synthetic methods of polyhexyl and per properties. p-Mononitropolystyrene seported in the previous papers, is reduced by sodium sulfide an aut oclave about 150°C to p-aminopolystyrene and the latter condenses with picrylchloride in vridine forming Picryl-p-Aminopolystyrene. Still more picryl-p-aminopolystyrene is nitrated by a mixed acid of nitric and nitric fuming to polyhexyl. This compound or resin is refined by dealing with 0.2 N NaOH and 0.2N H2SO4 continuously. This absorbs almost 100 % potassuim ions of calculated values and the selectivity curve in Na-K-Cl system is shown in Fig-2.
