Abstract

A membrane with osmotic properties comprises a porous film or fabric substrate onto which a porous polymer material support layer for a semi-permeable osmosis layer is applied. The support layer comprises a microporous structure of at least one polyethylene glycol diacrylate of formula (I) with an average molecular weight of 100-1000, containing a water soluble, hydrophilic gel in its pores. CH2=CH-CO-O-[-CH2-CH2-O-]n-CO-CH=CH2 (I) The preparation of this osmosis membrane is also claimed.
