MEMBRANES AND PROCESSES FOR THEIR MANUFACTURE AND USE

摘要

A process for preparing a membrane comprising the steps of: (i) Providing a composition comprising a polymerizable compound having at least 25 oxyethylene groups and at least two non-substituted vinyl groups; (ii) Applying said composition to a support thereby forming a continuous layer on the support; (iii) Polymerizing said composition thereby forming a non-porous polymer film. Also claimed are the resultant membranes and their uses, e.g. for separating polar and non-polar gases.
