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： Structured particle latexes are prepared by emulsion polymerizing monomeric materials in aqueous media in one or more stages wherein in at least one of the stages a reactive polymeric surfactant is used. The resulting latex contains nonionic particles to which are bound the reactive polymeric surfactant which forms a layer containing stabilizing "ionic" groups such as sulfonium groups, quaternary ammonium groups or sulfonate groups chemically bound at or near the surface of the polymer particles, which are dispersed in aqueous media. The cationic latexes are particularly suitable for beater additives and organic pigments.
