| 摘要 |
Provided are multifunctional polymers comprising at least one anhydride repeating unit with at least one pseudo-cationic moiety graft and at least one hydrophobic graft. The grafting functionalizations can occur before, during, or after polymerizing the monomer(s). The anhydride employed may be partially or fully opened to provide amic acids, carboxylic acids, carboxylic acidic salts, imides, esters, and mixtures thereof. The polymers also may comprise other repeating units, including, but not limited to, alpha-olefins. In one embodiment the polymers exhibit antimicrobial activity, and can be employed in a wide variety of compositions, including those where antimicrobial activity is useful. A method of providing microbial activity also is provided. |

1. A polymer comprising at least:
(A) at least a first repeating unit selected from the group consisting of: and combinations thereof, and (B) at least a second repeating unit selected from the group consisting of: and combinations thereof, wherein each C— indicates a bond from said unit to another unit along the polymer backbone; each R′ and R″ is independently selected from the group consisting of: hydrogen, alkyl, cycloalkyl, aryl, and combinations thereof, wherein said R′ and R″ may optionally form a ring; each R5 is independently selected from the group consisting of —NR9R10, functionalized and unfunctionalized nitrogen or phosphorus containing C5-C7 cyclic groups, and mixtures thereof; each R6, R8, R9, and R10 is independently selected from the group consisting of hydrogen, functionalized and unfunctionalized alkyl, alkoxy, cycloalkyl, alkenyl, cycloalkenyl, aryl, wherein any of the before mentioned groups may be with or without heteroatoms, and mixtures thereof; each R7 and R11 is independently selected from the group consisting of functionalized and unfunctionalized alkyl, alkoxy, cycloalkyl, alkenyl, cycloalkenyl, and aryl, wherein any of the before mentioned groups may be with or without heteroatoms, and mixtures thereof; each Q is independently selected from the group consisting of functionalized or unfunctionalized alkylene, cycloalkylene, and combinations thereof, wherein any of the functionalized or unfunctionalized alkylene may be with or without heteroatoms, and mixtures thereof; each E is independently selected from the group consisting of —OM, —OR7, —NHR7, —NR7R11, and mixtures thereof; and each M is independently selected from the group consisting of hydrogen, alkali metal ions, alkaline earth metal ions, ammonium ions, and mixtures thereof, and wherein said polymer has a weight-average molecular weight less than 50,000 Da. |
