The invention relates to water-in-oil polymer dispersions consisting of a continuous organic phase and water-soluble polymers finely distributed therein, wherein said polymers have a radical monomer content of less than 1,000 ppm. The invention also relates to a method for producing the inventive polymer dispersions and to their use as flocculation auxiliary agents, thickening agents and as additives for phytosanitary and anti-erosion agents.
La présente invention concerne des dispersions polymères eau dans huile composées d'une phase organique continue et de polymérisats finement répartis dans cette phase, lesdits polymérisats présentant une teneur en monomères résiduels inférieure à 1000 ppm. La présente invention concerne par ailleurs un procédé de fabrication des dispersions polymères selon l'invention et leur utilisation en tant qu'agent floculant, et en tant qu'additif de produits phytopharmaceutiques ou de produits de protection contre l'érosion.
