Claim 1: a dispersion comprising (a) a continuous Liquid Phase and (b) a Solid Phase epoxy Polymer particles dispersed in the continuous Phase Liquid where the polymer is formed from monomers which are insoluble in the continuous Phase there is a Chemical Agent present You In the polymer particles and the dispersion is not a dispersion of Pickering.Claim 2: a dispersion as claimed in claim 1, wherein the dispersion is not a dispersion of Pickering because is stabilized by a surfactant. Claim 3: a dispersion as claimed in claim 1 or 2, where the Agent is an agricultural Chemical active ingredient.Claim 5: a dispersion as claimed in any of the preceding Claims, wherein the continuous Phase (a) also comprises an Agrochemical active substance that is present as a Solution, an emulsion, a microemulsion or a suspension of microcapsules or couple Fine particles.Claim 6: a dispersion as claimed in any of the preceding Claims, wherein the polymer is a Polymer Matrix epoxy cured Epoxy Resin prepared from the curing of an Epoxy Resin selected among monomers and prepolymers of di - and poliep\u00f3 Oxide or mixtures of these with a HARDENER selected from primary and Secondary amines and their adducts,Cyanamide, dicianodiamida polycarboxylic acids, polycarboxylic acids, anhydrides, polyamines, Polyamides, polysulfides, poliaminoamidas poliaductos amines, Mercaptans, and poliep\u00f3xidos, polyols, and mixtures of these.Claim 7: a dispersion as claimed in any of the preceding Claims, wherein the epoxy Polymer particles comprising at least one Chemical Agent Mobile Cross linkable such that removal of this Chemical Agent from the particles makes the PA Rt\u00edculas become Porous, so that the active principle can leave by Diffusion.
