The invention provides asymmetric membranes composed of a microporous substrate whose pores contain a crosslinked gel, the density of the crosslinked gel being greater at or adjacent to one major surface of the membranethan the density at the other major surface. The membranesare useful for separating matter from liquids and display good flux and good rejection at low pressure.
