Abstract: A method of cross-linking polyacrylamide is provided which is particularly suited to the fabrication of battery separators. To an aqueous solution of polyacrylamide is added a chromiumcontaining compound wherein chromium is present at a valence of other than +3 and a compound which will react with said chromium containing compound to yield chromium ions at a valence of +3 which initiate cross-linking of the polyacrylamide.
