ABSTRACT:
Process for the preparation of polymer dispersions with particle diameters of 50 to 1000 nm, wherein there are employed, as emulsifiers for the emulsion polymerization citric acid derivatives of the general formula (I) ##STR1## in which, independently of one another, R.sub.1, R.sub.2 and R.sub.3 denote C.sub.6 -C.sub.20 -alkyl, (including cycloalkyl) hydrogen, sodium, potassium, lithium or ammonium and
