Use of terpolymers obtainable by free-radical copolymerization of (a) at least one anhydride of a C<SUB>3</SUB>-C<SUB>10</SUB>-dicarboxylic acid, (b) at least one 1,1-di(C<SUB>1</SUB>-C<SUB>3</SUB>-alkyl)-substituted C<SUB>4</SUB>-C<SUB>8</SUB>-olefin, (c) polyisobutene having a mean molecular weight M<SUB>n</SUB> in the range from 200 to 10 000 g/mol and, if appropriate, hydrolysis for producing aqueous emulsions or dispersions of hydrophobic substances using up to a maximum of 2% by weight of further emulsifier, based on the total aqueous emulsion or dispersion. |
