| 摘要 |
<p>The invention relates to a covalently cross-linked, asymmetrically porous membranes (M) made of thermoplastic silicone elastomers; a method for producing the covalently cross-linked, asymmetrically porous membranes (M), in which, in a first step, a solution of a silicone composition SZ, which contains thermoplastic silicone elastomer S1 with alkenyl groups and contains cross-linker V, and a solvent L is produced, in a second step, the solution is brought into a mold, in a third step, the solution brought into a mold is brought into contact with a precipitation medium F, wherein a covalently non-cross-linked membrane is formed. In a fourth step, the solvent L and the precipitation medium F are removed from the non-cross-linked membrane and, in a fifth step, the membrane is subjected to a cross-linking, wherein the covalently cross-linked membrane M is formed; the membranes (M) produced according to the method; and to the use of the membranes (M) for the separation of material mixtures or for coating.</p> |
