    Abstract: The invention relates to amphiphilic polymer compositions, to a method for their production and to their use for producing aqueous active ingredient compositions of water-insoluble active ingredients, in particular active ingredients for crop protection. The amphiphilic polymer compositions are obtained by reacting a) at least one hydrophobic polymer P1, which carries functional groups R1 that are reactive in relation to isocyanate groups and which is composed of ethylenically unsaturated monomers M1, comprising: a1) at least 10 wt. %, (in relation to the total quantity of the monomers M1), of monomers M1a of general formula (I), in which X represents oxygen or an N-R4 group; R1, R2, R3, and R4 are defined as cited in the claims and the description; a2) up to 90 wt. %, (in relation to the total quantity of the monomers M1) of neutral, monoethylenically unsaturated monomers M1b, whose solubility in water at 25 ~C is less than 50 g/l and which differ from the monomers M1a; and a3) up to 30 wt. %, (in relation to the total quantity of the monomers M1, of ethylenically unsaturated monomers M1c, which differ from the monomers M1a and M1b, b) at least one hydrophilic polymer P2, which carries functional groups R2 that are reactive in relation to isocyanate groups, c) with at least one compound V, which has a functionality of at least 1.5 in relation to the isocyanate groups.

    Abstract: The present invention relates to new comb polymers, to a method for the p roduction thereof, and to the use thereof for stabilizing water-insoluble or hardly soluble active or effective ingredients in an aqueous phase. The inv ention further relates to the use of the comb polymers in the production of active ingredient formulations or active ingredient preparations of water-in soluble active or effective ingredients, especially for agents for plant pro tection. The comb polymers can be obtained by copolymerization of monoethyle nically unsaturated monomers M, wherein the monomers M comprise: a) at least one monoethylenically unsaturated monomer Ma, selected from esters of monoe thylenically unsaturated C3-C8-monocarboxylic acids having C1-C20-alkanols, C5-C10-cycloalkanols, phenyl-C1-C4-alkanols or phenoxy-C1-C4-alkanols and th e diesters of monoethylenically unsaturated C4-C8-dicarboxylic acids having C1-C20-alkanols, C5-C10-cycloalkanols, phenyl-C1-C4-alkanols or phenoxy-C1-C 4-alkanols; and b) at least one monoethylenically unsaturated monomer Mb, se lected from the esters of monoethylenically unsaturated C3-C8-monocarboxylic acids and the monoesters and diesters of monoethylenically unsaturated C4-C 8-dicarboxylic acids having poly-(C2-C4-alkylene ether)ols, and wherein the total sum of the monomers Ma and Mb amounts atleast to 60 wt.% of the monome rs M constituting the comb polymer.
