POLYMER DISPERSING ADDITIVES FOR AGROCHEMICALS Russian patent published in 2022 - IPC A01N25/30 C08F12/08 C08F20/06 C08F22/20 A01N43/88 A01N51/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to polymer dispersing additives for active substances of agrochemical agents. Copolymer dispersing additive for an agrochemical agent compeises acrylic acid, a hydrophobic monomer, monoalkyl polyethylene glycol alkylacrylate, and, optionally, derivatives of (meth)acrylic acid with a strong acid, wherein the acrylic acid monomer used to form the copolymer is selected from (meth)acrylic acid or salts thereof, (meth)acrylamide, (meth)acrylonitrile, C1-6-alkyl(meth)acrylates substituted by C1-6-alkyl(meth)acrylates, di(C1-4-alkylamino)C1-6-alkyl(met)acrylates, amides formed from C1-6-alkylamines, substituted C1-6-alkyl amines or di(C1-4-alkylamino)C1-6-alkylamines, and (meth)acrylic acid and adducts thereof with C1-4-alkyl halide, wherein the hydrophobic monomer is selected from hydrophobic alkyl(meth)acrylates, styrene, and vinyl compounds, and vinyl aromatic monomers, wherein the molecular weight of the copolymer is in the range from 5,000 to 75,000 dalton. The copolymer dispersing additive is used in combination with an agrochemical active ingredient, and/or a nutrient, and/or a biostimulator for producing an agent.

EFFECT: proposed copolymer dispersing additive for an agrochemical agent ensures the homogeneity of the agrochemical agent, contributes to reduction and/or prevention of flocculation and agglomeration of particles of the agrochemical substance.
