    Abstract: The use of terpolymers, obtainable by free radical copolymerization of (a) at least one anhydride of a C 3 -C 10 -dicarboxylic acid, (b) at least one 1,1-di-(C 1 -C 3 -alkyl)-substituted C 4 -C 8 -olefin, (c) polyisobutene having an average molecular weight M n in the range of from 200 to 10 000 g/mol and, if appropriate hydrolysis, for the preparation of aqueous emulsions or dispersions of hydrophobic substances with the use of not more than 2% by weight of further emulsifier, based on the total aqueous emulsion or dispersion.
