The invention relates to a process for producing a polymer membrane, the polymer membrane being produced from a solution, in particular a casting solution, comprising at least one first polymer. The invention further relates to a polymer membrane. The process of the invention is distinguished by the fact that a water-soluble second polymer and/or oligomer that forms phases in the solution is part of the solution. The polymer membrane of the invention, preferably produced by the process of the invention, has an oil flow rate, in particular of a refined edible oil, of greater than 200 l/mh bar at 60&#xb0; C.

Process for producing a polymer membrane, and polymer membrane

A catalyst is produced by bonding a homogeneous catalyst to the surface of a catalyst support. A catalyst may include a catalyst support, a spacer molecule bonded to the catalyst support, and a homogeneous catalyst bonded to the spacer molecule. A catalyzed reaction can be carried out by providing reactants in a first phase and providing a catalyst as described herein in the first phase.

Immobilized homogeneous catalysts

A polymer electrolyte membrane includes a membrane polymer made of monomer units that have aromatic polyarylenes groups with proton-conducting functional groups bound to the aromatic polyarylene groups. The polymer electrolyte membrane can be used as a proton-conducting polymer membrane between the electrodes in a fuel cell.

Proton-conducting polymer membrane

Composite materials are provided. A representative material is configured as a composite membrane for gas separation, vapor separation, or pervaporation. The composite membrane comprises at least a first polymer and a second polymer. Processes for the production of composite materials, in particular composite membranes, also are provided.
