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.
摘要:
The invention relates to a process for the combinatorial investigation of the hardening of hardenable liquid or viscous formulations (a) in which n hardenable formulations are prepared in parallel in n containers, and (b) the degree of hardening is determined at least once on each of the n formulations by inserting a measurement tip into the formulation with a certain force and measuring the maximum penetration depth achieved as a measure of the degree of hardening of this formulation, and (c) for in each case one composition of the formulations, one or more parameters that are characteristic of the kinetics of hardening are determined from the measurement values for the penetration depth at various times after preparation of the formulations. Steps (a) to (c) are preferably carried out a number of times, and a dependence of the characteristic parameter(s) on the composition of the formulations is determined by analysis of the large number of individual values obtained in this way for the parameter(s) that is (are) characteristic of the kinetics of hardening, enabling the composition of the formulations to be optimized with respect to its hardening behavior.
