AGROCHEMICAL POLYMER DISPERSANT, AGROCHEMICAL AGENT, USE AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2015 - IPC A01N25/04 A01N25/14 A01N25/22 C08F220/06 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The agrochemical agent contains an agrochemically active substance and a polymer dispersant. The dispersant is a water-soluble polymer having the structure , where R₁, R₂ and R₃ are independently H, CH₃, COOH and CH₂COOH, a, b and c are the molar percentage of the individual groups, where a+b+c=100, a ranges from 0.1 to 95%, c ranges from 1 to 15% and b equals 100-a-c, X is a bridge group consisting selected from a group consisting of

R_hy is a hydrophobic residue which is selected from an alkyl with a linear or branched chain or an aryl; B is a residue obtained from polymerisation of a monomer of olefin-unsaturated carboxylic acid and salts thereof; and C is a residue obtained from polymerisation of a monomer of olefin-unsaturated sulphonic acid or a monomer of phosphonic acid and salts thereof. Said agrochemically active substance is selected from a group consisting of herbicides, insecticides, fungicides, biocides, molluscicides, algicides, plant growth regulators, anthelmintics, rodenticides, nematocides, acaricides, amebicides, protozoacides, antidotes for agricultural crops and auxiliary substances.

EFFECT: invention improves suspendability of the agent.
