Beschreibung
Zusammenfassung:	A composition comprising: a)5to 65wt% of curable compoundcomprising one ethylenically unsaturated group and at least one anionic group; b)2.5 to 70wt% of crosslinking agent comprising at least two acrylic groups; c)a tertiary amine; and d)0 to 45wt% of inert solvent; wherein the molar ratio of component c) to a) is at least 0.7. Also described are a process for making composite membranes and the resultant membranes.
