Abstract

Polymerpulvere som er redispergerbare i vandig løsning, anvendelse av disse i kosmetiske eller farmasøytiske preparater eller preparater for plantevern, samt en fremgangsmåte for fremstilling av polymerpulvere som er redisperger- bare i vandig løsning og som inneholder kopolymerer som bærer frie syre- eller basegrupper og eventuelt hjelpestoffer, kjennetegnet ved at man før tørkingen stiller dispersjonens pH-verdi ved tilsetning av minst ett buffersystem på 2,0 til 6,5 i tilfelle av syregruppeholdige kopolymerer eller pH 7,5 til 11 når det gjelder basegruppeholdige kopolymerer.
