| 摘要 |
The present invention relates to a method for the production of a solvent-stable polymer membrane, in which a poly(meth)acrylonitrile-comprising solution which comprises, at the same time, a crosslinker, is used. The solution can be poured as a film and the film can be crosslinked. Likewise, it is possible to spin a hollow thread membrane from the solution and subsequently to crosslink this. The thereby produced polymer membrane based on poly(meth)acrylonitrile or copolymers derived herefrom is distinguished by a crosslinking configured throughout. In addition, a solution is described, comprising a solvent and also, dissolved therein, a poly(meth)acrylonitrile or copolymer derived herefrom and also a crosslinker for the polyacrylonitrile which is suitable for the method according to the invention for the production of the polymer membranes according to the invention. |
