Abstract: Anew method for preparation of polystyrylsulfonyl chloride resin(l) is described in which the commercially available sulfonated ionic exchange resins (H⁺ form) were treated in ethanol with pyridine to convert into pyridinium polystyrylsulfonate, the latter was refluxed with thionyl chloride to give resin 1. Anumber of nitrogen-containing basic resins were obtained by the reaction of resin 1 with polyethylenepolyamines, α-aminopyridine, 1,2,4-triazole and 2-aminothiazole, respectively.

Key words: Polystyrylsulfonyl chloride, Polystyrylsulfonamide, Weak basic resin
