RESUMO

This thesis is divided in 3 parts. The first. part describes the performance of polysulfone-poly(vinylpirrolidone) blend membranes prepared by phase inversion and intended to be used in ultrafiltration. These membranes were characterized by scanning electron microscopy and by permeability measurements of aqueous solutions of poIy(ethyIene glycols) and dextrans, covering a range of MW s.
