MEMBRANE COMPRISING OXYETHYLENE GROUPS

摘要

The present invention relates to a membrane wherein said membrane comprises a continuous non-porous layer comprising a polymerized composition that comprised prior to polymerization at least one type of compound having a molecular weight of at least 1500 Da and comprising at least 75 weight% of oxyethylene groups and at least two polymerizable groups each comprising a non-substituted vinyl group. The invention further relates to the use of this membrane for separating polar gases and vapors.
