VERFAHREN ZUR HERSTELLUNG VON IN WASSER REDISPERGIERBAREN POLYMERPULVER-ZUSAMMENSETZUNGEN MIT KATIONISCHER FUNKTIONALITÄT
Water-redispersible polymer powder compositions having cationic functionality are prepared by radically polymerizing one or more ethylenically unsaturated monomers in the presence of a protective colloid and/or emulsifier in an aqueous medium, and drying the resulting aqueous polymer dispersion after addition of a catonic protective colloid as a drying aid, the cationic protective colloid comprising a homopolymer or copolymer of one or more cationic monomers having a quaternary ammonium halide group, with 50 wt % to 100 wt % of the halide ions in the quaternary ammonium halide groups having been replaced by nonhalide anions, and with the fraction of halide ions being less than 1 wt %, based on the total weight of the polymer powder composition.
