Hyperbranched polyethers/dendrimers for solubilzation of sparingly soluble active ingredients

摘要

The present invention provides an amphiphile of the formula (I) as described hereinafter. The invention further relates to a process for preparing the amphiphile and to a composition comprising the amphiphile and a sparingly water-soluble active ingredient. It further relates to a process for producing the composition by contacting the amphiphile and the active ingredient, and to the use of the amphiphile for solubilizing a sparingly water-soluble active ingredient in aqueous solutions. The invention also relates to the use of the amphiphile in an agrochemical formulation comprising the amphiphile and a pesticide for controlling phytopathogenic fungi and/or unwanted vegetation and/or unwanted insect or mite infestation and/or for regulating the growth of plants, and finally to plant propagation material comprising the amphiphile.

1. An amphiphile of the formula (I) where R1: each independently H, C1-C10-alkyl, —SO3—, —PO32−, —COO−, —R′—PO32−, or —R′—CO2—, where R′ is C1-C12-alkylene; R2: each independently C2-C5-alkylene, wherein at least 50 mol % of C2-alkylene is present in respect of R2; n: 1 to 200; m: 2 to 6; q: 0 to 50; Rp: a nonpolar polymer Rnp wherein said Rnp is NPa or NPb and wherein NPa is —C(O)(CHRa)2—CO2H, where Ra is independently H, C4-C44-alkyl, C4-C44-alkenyl, C6-C44-aryl, C7-C44-aralkyl or C7-C44-alkylaryl, and wherein at most one of the two Ra radicals is hydrogen; and NPb is —C(O)(CHRb)2—CO2H, wherein Rb is independently hydrogen or a poly(C2-C12-alkylene) group, which may optionally comprise at least one carboxylic acid group, a carboxylic anhydride group or an Rd radical bonded via a carboxylic ester group and wherein at most one of the two Rb radicals is hydrogen; and Rd: a nonpolar dendron Rnd.
