Abstract:
1. A composition comprising a water-soluble random copolymer formed from a hydrophilic first comonomer having an acrylate moiety comprising at least one of hydroxyethylmethacrylate, poly(ethylene glycol) methacrylate and poly(ethylene glycol) methyl ether methacrylate, and a second pyridinium-type comonomer containing a nitrogen atom and a vinyl moiety, wherein the first comonomer and the second comonomer are chemically bonded through the acrylate moiety of the first comonomer and the vinyl moiety of the second comonomer, wherein said nitrogen atom is quaternized with an alkyl moiety such that said polymer is polycationic, and wherein the amounts of the first comonomer and the second comonomer provide said water-soluble random copolymer with i. improved bactericidal activity as compared to the first comonomer or a homopolymer formed from the first comonomer; and ii. improved bactericidal activity as compared to the second comonomer or a homopolymer formed from the second comonomer.
