AGROCHEMICAL COMPOSITION BASED ON EMULSION POLYMERS Russian patent published in 2021 - IPC A01N25/04 A01N25/06 A01N43/40 A01N43/30 

FIELD: agriculture; chemistry.

SUBSTANCE: invention relates to agrochemical compositions based on emulsion polymers. An agrochemical composition contains a) an aqueous dispersion of at least one agrochemical active compound, which is solid at a room temperature, b) an emulsion polymer system, which is copolymer, containing I) stabilizing polymer and II) core polymer, c) one or more additives selected from a group consisting of non-ionic or anionic surfactants or dispersing auxiliary substances, d) rheological property modifiers, and e) other formulators. Wherein I) stabilizing polymer contains monomers based on acid and hydrophobic monomers having a mass ratio of the specified acid and hydrophobic monomer of 10-90:90-10, has a glass transition temperature (hereinafter – Tg) in the range from 30°C to 300°C and molecular weight of less than 100,000, and II) core polymer has Tg in the range from -100°C to 10°C. Formulators are selected from anti-foam products, biocides, means against freezing, dyes, pH regulators, buffers, stabilizers, antioxidants, inert fillers, humidifiers, inhibitors of crystal and/or microelement growth. The agrochemical composition is used as a means for non-root nutrition of plants, for the control of agricultural pests, weeds, diseases, as well as for improving resistance to rain and to washing away of an agrochemical active ingredient by rain, for reducing non-targeted losses to the environment of the agrochemical active ingredient.

EFFECT: invention allows obtaining an aqueous emulsion used as intended above, stable during storage.
