Abstract

Addition products of water-soluble sulfites or disulfites to maleic acid mono- or diesters of partially fluorinated alkanols or the mono-, di- or triethyleneglycol ethers of these alcohols are useful as surface active agents, especially as wetting agents, as levelling agents in wax emulsions or as dispersants.
