The present invention relates to a process for the preparation of an olefin polymer by condensation of a reactant comprising an ethene-type unsaturated reactant to form an ethene-type unsaturated polymer precursor, followed by sulfonation of the ethylenic unsaturation of the polymer precursor with a sulfonating agent such as bisulfite, meta bisulfite, Water-dispersible polymers, in particular polyesters, polyethers and polyamides. |
