Abstract: Copolymers based on N-vinylamide as adjuvant and compositions for the agrotechnical field The present invention relates to specific copolymers based on N-vinylamide and to their use as activity-improving adjuvant in the agrotechnical field and in particular in the field of plant protection. Appropriate agrotechnical compositions are likewise described. The copolymers are copolymers of vinylamides and ethylenically unsaturated carboxylic acid esters which are alkoxylated.

Abstract: Disclosed is a composition comprising (A) copolymer made up of (A-1) at least one ethylenically unsaturated, radically copolymerizable monomer of general formula Y—NR1—C(V)—NHR2, wherein the substituents have the following meaning: Y represents a radically polymerizable ethylenically unsaturated radical; V represents O, S, or NH; R1, R2 independently represent H or a C1 to C8 alkyl group or jointly represent a bridging C2 to C4 alkylene group that can be substituted up to twice with a C1 to C4 alkoxy group and/or hydroxyl group; (A-2) at least one unsaturated monomer of general formula X—C(O)CR7?CHR6, wherein the substituents have the following meaning: X is selected among the group of radicals —OH, —OR8, NH2, —NHR8, N(R8)2, radicals R8 being identically or differently selected among the group comprising —H, C1-C40 linear-chain or branched-chain alkyl radicals, N,N-dimethylaminoethyl, 2-hydroxyethyl, 2-methoxyethyl, 2-ethoxyethyl, hydroxypropyl, methoxypropyl, or ethoxypropyl; R7 and R6 are independently sele
