OSTWALD RIPENING INHIBITION IN CHEMICAL FORMULATIONS

摘要

A formulation having a slightly water soluble ingredient and method for preparing the same are disclosed. The millbase formulation comprises a slightly water soluble ingredient and a dispersant comprising a water soluble or water dispersible, derivative of an alternating copolymer or a salt thereof. The alternating copolymer comprises a residue of a first comonomer and a residue of a second comonomer. In addition, the first comonomer comprises an a,ß-unsaturated oxyacid, or an anhydride or other derivative thereof. Moreover, the second comonomer comprises an olefinic compound containing one or more polymerizable double bonds, or a derivative thereof. Such formulations may be used to inhibit Ostwald ripening in agricultural as well as non-agricultural applications.
