A method for the preparation of polymer membranes and polymer membrane

摘要

A method for the preparation of polymer membranes on the basis of a polymer solution and at least one particulate solid, comprising the steps ofa. shaping of the membrane-forming polymer solution andexample, removing the solvent from the shaped membrane-forming polymer solution,characterized in that, in order to obtain a microfiltration membranec. a suspension of a solvent and the particulate solid matter is formed,a highly concentrated polymer solution is used,e. that a dispersion of the solid in the solvent, andf. the polymer solution with the suspension is mixed in such a way that the resulting mixture of polymer solution and the suspension on the desired polymer concentration and the desired solids content is brought.
