Abstract
The present disclosure is generally directed to polymers comprising repeat units having the structures of Formulae 1, 2, and 3. These polymers are used in methods of removing contaminants, including PFAS and heavy metals, from an aqueous fluid comprising contacting the aqueous fluid with the polymer and in methods of catalyzing an organic transformation comprising contacting a fluid with a catalytic amount of the polymer.
Claims25
A polymer comprising repeat units having the structures of Formulae 1, 2, and 3
- wherein
- R1 is C1-C10 alkylene;
- R2 is hydrogen or —(CH2)x—C(R10)—C(O)—X—Z;
- R3 is hydrogen or —(CH2)x—C(R10)—C(O)—X—Z;
- R5 and R6 are independently hydrogen or —(CH2)x—C(R10)—C(O)—X—Z;
- R10 is hydrogen, alkyl, aryl, or alkaryl;
- R11, R12, and R13 are independently C1 to C10 alkyl or alkaryl;
- X is NH or O;
- Z is hydrogen, L1—NR11R12R13, L2—PR11R12R13, L3—COOH, L4—SO3H, L5—PO3H, or a salt thereof;
- and
- L1, L2, L3, L4, and L5 are independently C1-C10 alkylene or alkenylene;
- wherein the polymer comprises repeat unit of Formula 1 in an amount from 0 to 50 mole percent, Formula 2 in an amount from 30 to 99 mole percent, and Formula 3 in an amount from 1 to 20 mole percent, based on the total moles of the repeat units of Formula 1, Formula 2, and Formula 3.
