Salts from sulphonated dicarbon acids alkyl esters

摘要

Salt of mono- and/or dialkylester sulfonated dicarboxylic acid (I), where the dicarboxylic acid comprises 4-8 carbon atoms and the alkyl group is derived from 2-propylheptanol, is new. Independent claims are included for: (1) a composition comprising (I) and an organic solvent (which is a liquid at 20[deg]C) with a boiling point of greater than 250[deg]C at 1 bar; and (2) an aqueous polymer dispersion, obtained through emulsion polymerization in the presence of (I) as an emulsifier, crosslinker and/or auxiliary agent for post-stabilization.
