Patent

CA 2394948

The invention relates to a paste, which can undergo screen printing, for producing a porous polymer membrane. Said paste contains at least one polymer, one or more solvents for the poly-mer having a boiling point of > 100 °C, one or more non-solvents for the polymers (pore-forming agents) having a higher boiling point than that of the solvent(s), and contains a hydrophilic viscosity mod-ifier.

L'invention concerne une pâte pouvant être imprimée par sérigraphie, utilisée pour produire une membrane polymère poreuse, qui contient au moins un polymère, un ou plusieurs solvants pour le polymère ayant un point d'ébullition supérieur à 100 ·C, un ou plusieurs non-solvants pour le polymère (agents porogènes) ayant un point d'ébullition supérieur au(x) solvant(s), ainsi qu'un modificateur de viscosité hydrophile.
