The invention relates to a process for the preparation of polymer sulfides, which comprises treating compounds containing sulfoxide linking groups of the formula (I) -¢(Ar1)n-X!n-¢(Ar2)i-Y)!j-¢(Ar3)k-Z)!l-¢(Ar4!o-W)!p- (I) in which the symbols and indices have the following meaning: Ar1, Ar2, Ar3 and Ar4 are identical or different arylene systems having 6 to 18 carbon atoms, W, X, Y and Z are identical or different -SO2-, -S-, -SO-, -CO, -O-, -CO2-, alkylene or alkylidene groups having 1 to 6 carbon atoms, preferably 1 to 4 carbon atoms, where at least one linking group W, X, Y or Z must be an -SO- group, n, m, i, j, k, l, o and p are, identically or differently, 0 or an integer 1, 2, 3 or 4, where their total must be at least 2, a) thermally or b) in the presence of active hydrogen or c) photochemically and reducing to give the corresponding sulfides.
