ABSTRACT:
High boiling point polar organic solvent are useful solvents for poly(etheretherketone)-type polymers (PEEK). Solutions of PEEK may be used to form PEEK articles such as film, microporous sheet membrane, fiber and microporous hollow fibers. The microporous PEEK is useful as an ultrafiltration membrane and as a substrate for the formation of reverse osmosis membranes. A method of making PEEK articles including microporous sheet membranes is disclosed. A method of making PEEK fibers including microporous hollow membrane fibers is disclosed.
