CATIONIC POLYMERS COMPRISING HYDROPHOBIC GROUP AS DEPOSITION ENHANCERS FOR PESTICIDES AND CROP PRODUCTION CHEMICALS Russian patent published in 2017 - IPC A01N25/10 A01N25/24 A01N39/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Aqueous composition contains from 0.005 to 0.45 wt%, in terms of total weight of composition, at least one hydrophobically modified cationic polymer, obtained via polymerisation of monomers: (i) 5–80 wt% of alkyl ester of acrylic acid or alkyl ester of methacrylic acid, where alkyl group has 1-4 carbon atoms; and (ii) 5–80 wt% monomer, selected from a group, consisting of mono-or di-alkylamino alkyl(meth)acrylate, wherein alkyl group includes from 1 to 4 carbon atoms, and mono- or di-alkylamino alkyl(meth)acrylamide, selected from N,N-dimethylamino ethyl methacrylate (DMAEMA), N,N-diethylamino ethyl acrylate, N, N-diethylamino ethyl methacrylate, N-tert-butylamino ethyl acrylate, N-tert-butylamino ethyl methacrylate, N, N-dimethylamino propyl acrylamide, N, N-dimethylamino propyl methacrylamide, N,N-diethylamino propyl acrylamide and N,N-diethylamino propyl methacrylamide, and mixtures thereof; and (iii) 0.1–30 wt% binder monomer, selected from a group, including: (b) unsaturated copolymerisable surfactant monomer with ethylene bond, which is a product of condensation of nonionic surfactant, having a C₅-C₃₂-hydrocarbon group, with an unsaturated carboxylic acid with an ethylene bond; and (f) a hydrocarbon ester of acrylic acid or a hydrocarbon ester of methacrylic acid, where hydrocarbon group has from 5 to 32 carbon atoms; and (iv) 0–1 wt% cross-linking monomer; where weight percentages monomers are based on total weight of all monomers, present in polymerisation reaction; and one or more pesticides and/or chemicals for agricultural crops.

EFFECT: invention improves deposition of pesticides in production of agricultural crops.
