Abstract: Sulfonated and oxidized indene polymers obtainable by (a) polymerization of indene or indene derivatives of the general formula I I where R1 is hydrogen, methyl or ethyl and n is 1 or 2, or of mixtures which contain the compounds I as well as other copolymerizable and/or non-polymerizable organic compounds in an amount of at least 10% by weight, (b) sulfonation of the polymer with a sulfonating agent at from 40 to 130.degree.C, and (c) non-chain-degrading oxidation of the polymer at from 80 to 180.degree.C. These indene polymers are suitable for use as dispersants for example in dye and pigment preparations.
