    Abstract: The invention relates to a method for producing N,N'-carbonylbis- epsilon -caprolactam by the single-stage reaction of epsilon -caprolactam with phosgene, optionally in an inert organic solvent, in the presence of an organic nitrogenous base without an acylable nitrogen atom. The invention is characterised in that the organic nitrogenous base has a pKa-value of between 5 and 7. N,N-dimethylaniline is the preferred nitrogenous base.

    Abstract: The invention relates to a method for producing N,N'carbonylbis- epsilon -caprolactam by reacting epsilon -caprolactam with phosgene in the presence of a hydrogen chloride-binding agent in an inert organic solvent and isolating the reaction product from the product solution. The isolation comprises the following steps: a) optionally distilling off a part of the organic solvent from the product solution; b) adding water to the product solution; c) removing the organic solvent by azeotropic distillation, optionally while replacing the water distilled off, thereby deploying the product solution of organic solvent; d) allowing the N,N'-carbonylbis- epsilon -caprolactam to crystallize from the solution that is deployed from organic solvent, thereby obtaining an aqueous suspension of N,N'-carbonylbis- epsilon -caprolactam; and e) removing the crystallized product.

    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.
