摘要

The invention provides processes for preparing polyvinyl alcohol-stabilized polymers by means of free-radically initiated emulsion polymerization of one or more ethylenically unsaturated monomers, characterized in that one or more polyvinyl alcohols having a hydrolysis level of 92 mol% are metered in during the emulsion polymerization by means of pulse metering.
