    摘要: 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.

    摘要: The invention relates to a method for producing nanoparticles, in particular, pigment particles. Said method consists of the following steps: i) a raw substance (1) is passed into the gas phase, ii) particles are produced by cooling or reacting the gaseous raw substance (1) and iii) an electric charge is applied to the particles during the production of the particles in step ii), in a device for producing nanoparticles. The invention further relates to a device for producing nanoparticles, comprising a supply line (28) which is used to transport the gas flow (29) into the device, a particle producing and charging area in order to produce and charge nanoparticles at essentially the same time, and an evacuation line (30) which is used to transport the charged nanoparticles from the particle producing and charging area.
