Patent ID: 11130879

Abstract:
A graft copolymer is provided herein. The graft copolymer includes a polymeric backbone. The polymeric backbone includes a cyclic amine-containing moiety. The graft copolymer further includes a first side chain bound to the polymeric backbone, wherein the first side chain includes an acid-containing moiety. The graft copolymer further includes a second side chain bound to the polymeric backbone, wherein the second side chain includes an alkoxylated moiety. Another graft copolymer is provided herein. The graft copolymer includes a polymeric backbone. The polymeric backbone includes a quaternary ammonium moiety formed from a reaction of an amine-containing moiety and an alkylation agent. The graft copolymer further includes a first side chain bound to the polymeric backbone, wherein the first side chain includes an acid-containing moiety. The graft copolymer further includes a second side chain bound to the polymeric backbone, wherein the second side chain includes an alkoxylated moiety.
