Abstract: A filter material based on a polyarylene thioether having repeating units of the formula -[(Ar1)n-X)]m-[(Ar2)i-Y)]j-[(Ar3)k-Z)]l-[(Ar4)o-W)]p-(I) in which Ar1, Ar2, Ar3, Ar4, W, X, Y and Z, independently of each other, are identical or different, the indices n, m, i, j, k, l, o and p, independently of each other, are zero or integers 1, 2, 3 or 4, their sum being at least 2, Ar1, Ar2, Ar3 and Ar4 are arylene systems having 6 to 18 carbon atoms, and W, X, Y and Z are divalent linking groups, selected from -SO2-, -S-, -SO-, -CO-, -O-, -CO2-, or alkylene groups or alkylidene groups having 1 to 6 carbon atoms is suitable for removing ozone from gases or liquids. The removal proceeds quantitatively, no volatile products being formed.
