Abstract
Described herein are antimicrobial copolymers comprising (i) a polymer backbone and a plurality of thiouronium groups covalently bonded to the polymer backbone and (ii) a plurality of quaternary ammonium groups covalently bonded to the polymer backbone. Also described herein are methods for making the copolymers described herein and their use in disinfecting compositions.
Claims17
An antimicrobial copolymer comprising
- (i) a polymer backbone and a plurality of thiouronium groups covalently bonded to the polymer backbone,
- wherein the thiouronium group has the structure
- wherein R1 is an aryl group, an alkylene group, or an aralkyl group that is covalently bonded to the polymer backbone, and R2 and R3 are independently hydrogen, an alkyl group, or an aryl group;
- and
- (ii) a plurality of quaternary ammonium groups covalently bonded to the polymer backbone, wherein the quaternary ammonium group has the structure
- wherein R5 is an aryl group or an alkylene group and is covalently bonded to the polymer backbone, and R6, R7, and R8 are independently an alkyl group or an aryl group;
- wherein the copolymer comprises the polymerization product between a first olefinic monomer having a thiouronium group and a second olefinic monomer having a quaternary ammonium group;
- and
- wherein each thiouronium group and quaternary ammonium group has a counteranion.
