ABSTRACT:
The polymeric nanoparticles including olfactive components have a glass temperature of >50° C. They are obtainable by continuously adding a monomer component and an olfactive component to an aqueous solution. The aqueous solution comprises a first initiator and an emulsifier. The added components are distributed in the aqueous solution to obtain reaction mixture while the polymerization of the monomer component is started at the first temperature. The liquid monomer component and the olfactive component are added continuously while a second initiator is added dropwise to the reaction mixture and the first temperature is maintained. After terminating the addition of liquid monomer component and the olfactive component the temperature of the reaction mixture is increased to a second temperature and a third initiator is added dropwise.
