主权项 1. A polymer comprising: a first repeating unit selected from the group consisting of:and combinations thereof, wherein each X is independently selected from the group consisting of O, NR1, and combinations thereof; each R1 and R2 is independently selected from the group consisting of hydrogen, halogen, and functionalized and unfunctionalized hydrocarbyl optionally having one or more heteroatoms; each R3 is independently selected from the group consisting of hydrogen, U, and functionalized and unfunctionalized hydrocarbyl optionally having one or more heteroatoms; each M is independently selected from the group consisting of alkali metal ion, alkaline earth metal ion, ammonium ion, and combinations thereof; each U has a structure independently selected from the group consisting of:and combinations thereof, wherein each R31, R32, R33, R34, R35, R41, R42, R43, R44 and R45 is independently selected from the group consisting of hydrogen, halogen, amino, alkyl amino, hydroxyl, alkoxyl, sulfonyl, carboxyl, functionalized and unfunctionalized hydrocarbyl optionally having one or more heteroatoms, and combinations thereof; each Y is independently selected from the group consisting of O, NR1, S, and combinations thereof; each Q is independently selected from the group consisting of functionalized and unfunctionalized hydrocarbylene optionally having one or more heteroatoms; and each (wavy bond) indicates the point of attachment for each said U.
