Abstract
A process for making a composite membrane comprising the steps: (i) providing a moving poriferous support () impregnated with a curable composition, wherein the composition is present in the pores of the support and on a surface of the support; (ii) scraping or squeezing the poriferous support and thereby removing at least some of the curable composition () from the surface of the support; and (iii) after performing step (ii), irradiating the support, thereby curing the composition present therein. Composite membranes are also claimed having a surface layer thickness of below 0,5 microns.
