Abstract
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 polymer 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 modifier.
