    摘要: Stable emulsions of water-insoluble organic pesticides are formed by mixing the pesticide with an aqueous dispersion of a graft copolymer comprising a reactive polymeric surfactant base polymer and a nonionic hydrophobic grafted composition. The graft copolymer spontaneously absorbs organic pesticides with low water solubility upon simple mixing. The resulting product is much more stable to coalescence than emulsions made with conventional or polymeric surfactants.Emulsifiable organic based concentrates, having a continuous oil phase, which are formed from admixtures of pesticidally active water-insoluble organic pesticides with graft copolymers can be diluted with or in water, thus, inverting the continuous oil phase to stable water based oil-in-water emulsions of the active pesticide.

    摘要: Stable, aqueous emulsion formulations of water-insoluble organic pesticides are formed from a mixture of (1) a water-insoluble organic pesticide, (2) a water based structured particle latex containing nonionic particles to which is bound a layer containing stabilizing pH independent ionic groups chemically bound at or near the surface of the polymer particles, and optionally a cosolvent and/or cosurfactant for the pesticide. The resulting product is much more stable to coalescence than emulsions made with conventional surfactants.
