Abstract
Polymers having antibacterial activity are disclosed. The polymers are water-dispersible vinyl copolymers comprising (a) from 15 to 90 mole percent of recurring polymerized vinyl monomer units having a quaternary nitrogen cationic group containing an alkyl substituent having 14 to 20 carbon atoms and (b) from 10 to 85 mole percent recurring polymerized vinyl monomer units having a quaternary nitrogen cationic group having one or more alkyl substituents containing less than 14 carbon atoms.
