Processes for the production of polymers by emulsion polymerization of olefinically unsaturated monomers, in which olefinically unsaturated esters corresponding to formula (I): HOOC—CH═CH—COO—(BO)z(PO)y(EO)xR1  (I) in which R1 is an alkyl group or alkenylphenol group containing 8 to 24 carbon atoms, BO is a butylene oxide unit, PO is a propylene oxide unit and EO is an ethylene oxide unit and the indices x, y and z independently of one another stand for 0 or for numbers of 1 to 50, with the proviso that at least one of the indices x, y and z is not 0, the carboxyl group of the compounds (I) being completely or partly present in neutralized form and the C═C double bond being cis- or trans-configured; are used as copolymerizable emulsifiers.
