Abstract
The copolymer 7 of quaternary ammonium salt, N,N-diallyl-N- carboethoxymethyl-N-methylammonium chloride (5) and sulfur dioxide were synthesized in excellent yield. The polyelectrolyte 7 on acidic hydrolysis gave the polyampholyte 8 readily in excellent yield. The solution properties of these polymers are discussed in detail. The polyampholyte 8 was found to be insoluble in water but dissolved readily in the presence of low molecular weight common salts. The polyampholyte shows 'anti-polyelectrolyte' behavior; the viscosity of the polyampholyte increases by increasing the ionic strength of its aqueous solutions.
