Notes:
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.
