Beschreibung
Zusammenfassung:	The invention relates to polymer dispersions, methods for their preparation and their use. The polymer dispersions are prepared in a radical polymerization reaction which is initiated by a combination of different initiators. The polymer dispersions are useful inter alia as flocculants, dewatering (drainage) aids and retention aids in papermaking. L'invention concerne des dispersions polymères, des procédés pour leur préparation et leur utilisation. Les dispersions polymères sont préparées dans une réaction de polymérisation radicalaire qui est amorcée par une combinaison de différents initiateurs. Les dispersions polymères sont utiles, entre autres, comme floculants, auxiliaires de déshydratation (drainage) et auxiliaires de rétention dans la fabrication du papier.
