Abstract
Compounds, polymer compositions, systems, and methods for determining a concentration of a polymer composition in a fluid. The polymer compositions may include a copolymer that includes a tagging monomer. The copolymer may have a molecular weight of at least 1,000,000 Da (Mw). Methods for synthesizing compounds and polymer compositions.
Claims15
A polymer composition comprising:
- a copolymer comprising—
- (i) a first monomer comprising (a) a compound of formula (I), formula (I′), or formula (I″), or (b) a compound or an isomer of formula (II), 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 R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R23, R24, R25, R26, R27, and R28 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 R40 is selected from the group consisting of C1-C6 alkoxy, C2-C6 alkenoxy, C2-C6 alkynoxy, —N(R′), —N(R′)(R″), C2-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, and
- wherein the isomers of Formula (II) comprise a compound of Formula (IIi), a compound of Formula (IIii), a compound of Formula (IIiii), or a combination thereof—
