Foamed polystyrene, known commonly as Styrofoam, is a non-degradable polymer of high molecular weight and accounts for 30% of all landfill waste. Due to its robust mechanical integrity and large application base, foamed polystyrene is an important target to find degradable alternatives for. Previously, the Bates' lab has shown that addition of lipoate monomers to acrylate polymers enables chemical degradability through the introduction of labile disulfide bonds in the backbone. This project aims to explore the applications of foamed-degradable-styrenic polymers through the incorporation of ethyl lipoate into the carbon backbone. Current methodology applies inverse aqueous emulsions for polymerization of the continuous phase to produce open-cell foams. Based on the loading of ethyl lipoate, foams of varying mechanical integrity have been successfully synthesized, with promising results on their chemical degradability.
