ABSTRACT:
The present invention relates to the use of a hydrophilic, biocompatible and biodegradable elastomer membrane or film for the selective separation of a gas mixture. Accordingly, processes for selective gas separation of a gas mixture are provided in which a gas mixture is contacted with such a membrane such that a selective portion of the gas mixture passes through the membrane.
