Polysulfone-based Hollow Fiber Membrane Having Excellent Chemical Resistance and Preparation Method Thereof

摘要

The present invention relates to a polysulfone-based hollow fiber membrane excellent in chemical resistance and a method for producing the same. In addition to the molecular weight of the pore-forming agent and the molecular weight and content of the polysulfone-based matrix resin, By optimizing the content, it is possible to provide a polysulfone-based hollow fiber membrane excellent in mechanical strength and water permeability as well as excellent in chemical resistance.
