Abstract
A process for preparing vinyl acetate-ethylene copolymers in the form of an aqueous dispersion. The process includes providing an aqueous dispersion of vinyl acetate-ethylene copolymers and subjecting the aqueous dispersion of vinyl acetate-ethylene copolymers to radically initiated emulsion polymerization in a continuously operated tubular-reactor. Where one or more dividing plates bearing liquid-permeable openings that are mounted within the tubular-reactor transverse to the flow direction of the reactor contents.
