Abstract
A composition contains ethylenically unsaturated quaternary ammonium cations with acetate counterions, where each of the ethylenically unsaturated ammonium cations contain only one non-aromatic carbon-carbon double bond and the composition contains less than one mole-percent chloride relative to quaternary ammonium cations can be polymerized to form a cationic polymer acetate.
Claims7
A method for producing a cationic polymer from a composition comprising ethylenically unsaturated quaternary ammonium cations with acetate counterions where each of the ethylenically unsaturated ammonium cations contain only one non-aromatic carbon-carbon double bond and the composition contains less than one mole-percent chloride relative to quaternary ammonium cations, the method comprising polymerizing the ethylenically unsaturated quaternary ammonium cations by free radical polymerization of the carbon-carbon double bond so as to produce a cationic polymer having quaternary ammonium pendant functionality with acetate counterions.
A cationic polymer having multiple quaternary ammonium pendant functionalities with acetate counterions.
