The quaternary ammonium salt 1,1‐diallyl‐4‐formylpiperazinium chloride ( 7 ) was synthesized in good yields. The monomer ( 7 ) on cyclopolymerization in the presence of ammonium persulfate in water solution at 90°C afforded water‐soluble polymer ( 8 ) having excellent rheological properties. The synthesis of the polymer ( 8 ) paves the way for the preparation of a novel class of polymers: dicationic polyelectrolytes ( 9 ) and cationic polymer ( 10 ) with a basic nitrogen as well as a quaternary nitrogen. Effects of monomer, initiator, and additives concentration were studied. Cyclopolymerization of ( 7 ) with 1,1,4,4‐tetraallylpiperazinium dichloride ( 12 ) gave ion‐exchange resins with excellent swelling coefficients. © 1996 John Wiley & Sons, Inc.
