    摘要: A method for providing urea particles in a solvent medium, said method comprising at least the steps of:providing at least one polyisocyanate component dissolved in a first solvent;providing at least one isocyanate-reactive polyamine component dissolved in a second solvent;providing at least one isocyanate-reactive monoamine, optionally dissolved in a third solvent;combining and reacting said isocyanate-reactive monoamine optionally dissolved in said third solvent with said polyisocyanate dissolved in said first solvent, thereby providing an urea-modified polyisocyanate dissolved in said first solvent and said optionally third solvent, and thencombining and reacting said urea-modified polyisocyanate dissolved in said first solvent and said optionally third solvent with said polyamine component dissolved in said second solvent.
