A is substituted or unsubstituted C 1-36 hydrocarbylene, divalent heteroaryl, or ether; and
m is 0 or 1,
wherein the polymer has a number average molecular weight of 20,000 g mol −1 or greater.

2. The polymer of claim 1 , wherein the polymer is coordinated with a high dielectric constant ligand.

3. The polymer of claim 2 , wherein the high dielectric constant ligand is water; ammonia; hydrogen sulfide; an alcohol; an amine; or a thiol.

4. The polymer of claim 1 , wherein R 1 and R 2 are each independently unsubstituted C 1-6 alkyl.

5. The polymer of claim 1 , wherein R 1 and R 2 are each methyl.

6. The polymer of claim 1 , wherein A is substituted or unsubstituted C 1-12 alkyl, substituted or unsubstituted C 3-12 cycloalkyl, substituted or unsubstituted C 6-12 aryl, substituted or unsubstituted C 3-6 heteroalkyl, substituted or unsubstituted C 2-12 alkenyl, substituted or unsubstituted C 2-12 alkynyl, substituted or unsubstituted C 6-12 heteroaryl, or substituted or unsubstituted C 1-36 alkyl whose chain is interrupted by one or more units of substituted or unsubstituted C 6-12 aryl or one or more units of substituted or unsubstituted C 6-12 heteroaryl.

7. The polymer of claim 1 , wherein A is substituted or unsubstituted C 1-12 alkyl.

8. The polymer of claim 1 , wherein A is —O—(—R 4 —O—) n — wherein each R 4 is independently a divalent C 1-8 alkyl or divalent C 3-12 cycloalkyl, and n is 1 to 12.

9.
