Abstract
Subjects of the invention are processes for preparing vinyl acetate-ethylene copolymers in the form of their aqueous dispersions or water-redispersible powders by means of radically initiated emulsion polymerization and optional subsequent drying of the resultant polymer dispersions, characterized in that the emulsion polymerization of vinyl acetate, ethylene and optionally one or more further ethylenically unsaturated monomers is carried out in the presence of one or more protective colloids in one or more Taylor reactors.
