Abstract: Foam compositions are provided. The compositions are prepared from multi-functional acetoacetate esters and multi-functional amines or acrylates. The foam compositions can include one or more additives. The foam compositions can be used for home and commercial insulation, air sealing, sound proofing, structural improvement, and exterior roofing, among other applications. The foam compositions provide advantages of being isocyanate free and offer reduced exposure to isocyanate.
