Claim 0:
1. A polymer composition comprising:
a copolymer comprising—
(i) a first monomer selected from the group consisting of (a) a compound of Formula (I), (b) a compound of Formula (II), (c) a compound or isomer of Formula (III), and (d) a compound or isomer of Formula (IV), wherein the first monomer is a tagging monomer, and
(ii) at least one second monomer comprising at least one polymerizable double bond or at least one polymerizable triple bond, wherein the at least one second monomer is a scale-inhibiting monomer;, wherein R1, R2, R3, R4, R5, R6, R7, R8, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R23, R24, R25, R26, R27, R28, R29, R30, R33, R34, R35, R36, R37, R38, R39, R40, R41, R42, R43, and R44 are independently selected from the group consisting of hydrogen, hydroxyl, C1-C6 alkoxy, C2-C6 alkenoxy, C2-C6 alkynoxy, —N(R′)(R″), C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, and C4-C14 aryl,
wherein R′ and R″ are independently selected from the group consisting of hydrogen and C1-C6 alkyl,
wherein R9, R10, R31 and R32 are independently selected from the group consisting of hydrogen, hydroxyl, C1-C6 alkyl, and C1-C6 alkenyl,
wherein y is a single bond or a double bond, and
wherein z is a single bond or a double bond;
wherein the isomers of Formula (III) comprise a compound of Formula (Illi), a compound of Formula (IIIii), a compound of Formula (IIIiii), or a combination thereof —, and
wherein the isomers of Formula (IV) comprise a compound of Formula (IVi), a compound of Formula (IVii), a compound of Formula (IViii), or a combination thereof—,
