Abstract
Procedure for obtaining polyvinyltriorganosilane membranes, of the type comprising a polymer film with a thickness of between 50 and 500, with each of its two faces having pores with a diameter of between 0.05 and 25, passing through at least a part of these pores without discontinuity the entire thickness of the membrane, characterized in that it comprises a) forming a solution of a polymer, comprising a plurality of motifs of the formula ** formula ** in which the symbols, R1, R2 and R3, are identical or different, represent a linear or branched alkyl radical containing from 1 to 12 carbon atoms, a cycloalkyl radical with 5 or 6 carbon atoms in the cycle, a monovalent, mono or polycyclic aromatic radical, and may be the cycloalkyl and/or aryl radicals have been replaced by one or more alkyl radicals having 1 to 4 carbon atoms, and one of the radicals R1, R2 and R3 may also represent an α I take hydrogen, a solvent and a non-solvent of this polymer, solvent and non-solvent being miscible with each other, b) casting solution a) on a temporary support; c) contacting the layer thus formed with a polymer coagulation liquid before any evaporation of the solvent and/or non-solvent, and d) separating the membrane from the support and drying it.
