Abstract
The invention relates to a method for polymerizing ethylenically unsaturated monomers by free-radical initiated emulsion polymerization in an aqueous medium in a polymerization reactor, wherein the inside walls and optionally also the fittings in the reactor are coated by applying a deposit-inhibiting product before the reactor is filled, characterized in that the surfaces that are to be coated with deposit-inhibiting product are treated with an acid solution.
