Dispersions stabilised by cross-linked polymeric dispersants

摘要

Disclosed is a dispersion of an agrochemical which is either an agrochemical active ingredient or an agrochemical adjuvant, said dispersion comprising a discontinuous phase of solid particles comprising the agrochemical or liquid droplets comprising the agrochemical which have an average diameter of between 1000 microns and 0.1 microns; a liquid continuous phase; a polymeric dispersant physically adsorbed at the interface between the continuous phase and the discontinuous phase, having a segment soluble in the continuous phase and a segment insoluble in the continuous phase; and a network around the solid particles or the liquid droplets formed by cross-linking of the polymeric dispersant; where the cross-linking involves a reactive moiety located within the segment that is soluble in the continuous phase.
