Process for the preparation of polyvinyl alcohol-stabilized polymers by emulsion polymerization

摘要

The invention relates to processes for the preparation of polyvinyl alcohol-stabilized polymers by means of radically initiated emulsion polymerization of one or more ethylenically unsaturated monomers, characterized in that one or more polyvinyl alcohols with a degree of hydrolysis of ≥ 92 mol% are metered in during the emulsion polymerization by means of surge metering.
