POLYMERIC COMPOSITE PARTICLES

Compositions are provided that include a matrix and a polymeric composite particles disposed in the matrix. The polymeric composite particles include a porous polymeric core and a fragrance positioned within the porous polymeric core. Polymeric composite particles are also provided including a porous polymeric core, a fragrance positioned within the porous polymeric core, and a coating layer around the porous polymeric core. Further, a method of determining a minimum temperature of a composition is provided including providing a composition including polymeric composite particles disposed in a matrix, heating the composition, releasing at least a portion of the fragrance as a vapor from the porous polymeric core of the polymeric composite particles at or above the minimum temperature, and detecting at least a portion of the fragrance vapor in a location outside of the matrix.
