Abstract
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 of flocculation auxiliary agents, thickening agents and as additives for phytosanitary and anti-erosion agents.
Claims22
A water-in-oil polymer dispersion, comprising a continuous organic phase comprising 20 to 80 wt % of a fatty acid ester that is practically immiscible with water, and a water-soluble polymer, and optionally one or more auxiliary agents finely distributed therein, and wherein said dispersion has a residual monomer content of less than 1000 ppm.
