ABSTRACT:
Microporous polysulfone membranes can be prepared by using a particular combination of casting solution and precipitation solution formulations, and casting conditions. The casting solution comprises polysulfone and a protein non-adsorptive prepolymer and the precipitation solution comprises a polymerization catalyst. Both hollow fiber and flat membranes can be prepared in this manner. The membranes are substantially protein non-adsorptive and have valuable physical characteristics including increased strength and high flux.
