摘要:
A process for preparing a composite membrane comprising the steps: a)applying a radiation-curable composition to a porous support; b)irradiating the composition and thereby forming a gutter layer of cured polymer; and c)forming a discriminating layer on the gutter layer; wherein the radiation-curable composition comprises a partially crosslinked, radiation-curable polymer comprising epoxy groups and siloxane groups, a photoinitiator and is substantially free from mono-epoxy compounds. Composite membranes and gas separation cartridges are also claimed.
