Polymer composition, membrane containing said composition, method for the production and uses thereof

The invention relates to a process for separating off ethylene from a gas mixture comprising more than 8% by volume of carbon dioxide or oxygen, by gas permeation.

Ethylene treatment by gas permeation

The invention relates to a process for preparing carbonyl compounds from olefins and an oxidizing agent in which the olefin is oxidized in a reactor, a reaction gas mixture which comprises unoxidized olefin being formed, which comprises separating off unoxidized olefin at least in part from the reaction gas mixture by a membrane process.

Preparation of ethylene by gas permeation

Method for producing a membrane used to operate fuel cells and electrolyzers

Process for using microwave irradiation to prepare solutions of polymers functionalized with acid groups The invention relates to a process for preparing aqueous, hydrous and anhydrous solutions of polymers functionalized with acid groups, which comprises using microwave radiation to supply the heat required to prepare the solution. The solutions are suitable as a starting material for producing gas diffusion electrodes, fuel cells and polymer-electrolyte-stabilized platinum nanoparticles.
