Abstract

@ The present invention concerns a process for preparing an aqueous dispersion of water-soluble core/shell particles by emulsifiying a mixture comprising at least one hydrophobic solvent and/or organic target material, at least one hydrophobic solvent, 3, 4, 5 and 6. The emulsified mixture is heated to polymerise the initial monomer, and then at least one base selected from ammonia and the organic amines is added to neutralise the polymerised carboxylic acid to form core/shell particles. Optionally, additional monomer is added whereby said addition monomer is polymerised on or in the previously found shell of said core/shell polymer.Compositions comprising said core/shell particles are useful as or in coating composition, herbicidal compositions or biocidal compositions.
