Abstract
The present invention relates to novel pervaporation membranes comprising a porous support layer upon which a thin coating is applied. More specifically, the present invention provides pervaporation membranes with an improved performance by applying an aggregate filled PTMSP coating with a maximal thickness of 25 μm onto the porous support. The present invention further relates to methods of the manufacturing of such pervaporation membranes.
