Hydrophilic polymer and membrane for oil-water separation and method of producing the same

摘要

This invention relates to a hydrophilic polymer and membrane for oil-water separation. More particularly, this invention relates to a super hydrophilic polymer and membrane with zwitterionic property for oil-water separation, and method of producing the same. The hydrophilic polymer comprises polymer repeat units, each unit having at least one negatively charged carboxylic functional group and at least one positively charged amine functional group; and a monomer having a single aromatic ring and an imide functional group.
