Claims20
A process for preparing a microcapsule slurry, comprising the steps of:
- 1) suspending coacervate particles in a solvent to form a dispersing phase;
- 2) admixing at least one polyfunctional monomer with a hydrophobic material to form an oil phase;
- 3) adding the oil phase to the dispersing phase and mixing them to form a two-phase Pickering emulsion under conditions allowing the formation of a microcapsule slurry by interfacial polymerization.
