ABSTRACT:
The invention relates to nanoparticulate formulations comprising at least one active compound or compound with a special effect and at least one random radical copolymer. The copolymers are formed from monomers carrying sulfonic acid groups and additional olefinically unsaturated compounds.The formulations are dispersible as nanoparticles in an aqueous medium. The invention includes, in addition, processes for the preparation of the solid and liquid formulations, and their use.
