  • Hydrophilic polymer membranes made of single phase polymer blends comprising polysulfones and hydrophilic copolymers
    Publication number: 20040102587
    Abstract: A polymer membrane having a first surface and a second surface, wherein the polymer membrane has a reticulated network of flow channels between pores on the first and second surfaces, and is made of a single phase blend containing a polysulfone polymer and a poly(vinylpyrrolidone-co-styrene) copolymer, the content of the poly(vinylpyrrolidone-co-styrene) copolymer contained in the polymer membrane being such that the poly(vinylpyrrolidone-co-styrene) copolymer can form the single phase blend with the polysulfone polymer.
