Abstract: Provided herein are compositions containing a polymer substrate and a fragrance, methods for preparing such compositions, and methods for using such compositions for providing scents to an environment, such as a room or a vehicle. For example, the polymer substrate may comprise an alkyl acrylate, including but not limited to methyl acrylate. For example, the fragrance may comprise a polar or nonpolar molecule, or a collection of polar and/or nonpolar molecules. The resulting composition provides a temperature-stable fragrance composition that can be used within vehicles, has low to no residual odor, and can be loaded with at least 90% by weight of fragrance (relative to the weight of the polymer substrate).
