Abstract (en)
[origin: WO2020221435A1] The invention relates to a method for producing aqueous polymer dispersions by means of radically initiated emulsion polymerisation of ethylenically unsaturated monomers in the presence of protective colloids and/or emulsifiers in a continuously operated tube reactor, characterised in that the direction of flow of the reactor contents is reversed along the longitudinal axis of the rector at regular time intervals.
