Abstract
Polymers and membranes with acrylamide moieties are disclosed herein. A disclosed copolymer includes first repeat units of an acrylamide moiety and second repeat units of a hydrophobic moiety. The molar ratio of second repeat units:first repeat units is between 0.8:1 to 2.5:1 based on a molar ratio of the respective monomers in a production feed. The disclosed copolymer can also include a crosslinker. The amount of cross-linker in a corresponding monomer feed is 0 to 1 mol %, based on the total monomer in the production feed.
