Abstract

The invention relates to a hyperbranched polymer comprising:a) a hyperbranched polycondensate with hydroxyl end groups, amino end groups, or a combination thereof condensed tob) one or more linking groups connected toc1) one or more polyethylene glycol monomethyl ethers andc2) one or more poly(C2-C3)alkylene glycol mono-(C8-C22)-alkyl ethers, wherein the weight ratio of components c1):c2) is from 9:1 to 1:9. It further relates to a process for producing the polymer, to a composition comprising the polymer and an active ingredient, and to a method for controlling phytopathogenic fungi or undesired vegetation or insect or acarid infestations or for regulating the growth of plants.
