Rezumat:

Application of phase inversion method, in particular immersion-precipitation technique has allowed the obtaining of polysulfone and polyphenyleneoxide membranes from solutions of aprotic solvents as: dimethylformamide, dimethylacetamide, N-methylpirolidone, chloroform and trichlorethylene. The membranes were obtained according to the pathways indicate by Smolders on polymer-solvent-non-solvent phase diagram.
