Abstract
Agrochemical and other particulate compositions are formed by coacervation. The coacervate is preferably formed from two water soluble coacervating polymers and stabilizes the particles against agglomeration. The coacervate is preferably formed from a relatively low molecular weight cationic polymer and a relatively high molecular weight anionic polymer.
