    Abstract: 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.

    Abstract: Articles are provided, including a substrate having a first major surface, the substrate including a nonwoven material, a woven material, or a foam. The article further includes microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules, where the plurality of microcapsules is attached to the first major surface of the substrate with a polymeric material. A method of making an article is also provided, including providing a substrate having a first major surface and providing microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules. The method further includes attaching the microcapsules to the first major surface of the substrate with a polymeric material, thereby forming a polymeric matrix attached to the first major surface of the substrate.

    Abstract: Coextruded polymeric article comprising first segments each having first and second opposed major surfaces and a thickness, the first segments comprising first material; second segments comprising second material, wherein adjacent first segments are joined together via a second segment, wherein at least 10 percent by number of the second segments extend from the second major surface past the first major surface of each first adjacent segment and has a distal end, the second segments having first and second opposed major surfaces, wherein there is a gap between adjacent second segments; and adhesive on the first and second major surfaces of at least every other second segment except a portion of the major surface adjacent to the respective distal end is free of the adhesive, wherein the first segments, second segments, and adhesive each extend continuously for at least 5 mm. Uses for coextruded polymeric articles described herein include adhesive articles and household cleaning products (e.g., as mops, dusters, brushes, cleaning cloths, and lint rollers).
