The quaternary ammonium salt, N,N-diallyl-N-carboethoxymethyl-N-methylammonium chloride (7), has been synthesised in excellent yield. The monomer (7), on polymerisation in water solution using ammonium persulfate as an initiator, afforded the polyelectrolyte 8. The polyelectrolyte (8), on acidic hydrolysis, gave the polyampholyte 9 in excellent yield. The solution properties of these polymers are discussed in detail. The polyampholyte 9 showed 'antipolyelectrolyte’ behaviour.
