Frontal polymerization of deep eutectic solvents (DESs) made with acrylic or methacrylic acid as the monomer and hydrogen bond donor was studied. Fronts with acrylic acid and choline chloride propagated more uniformly than with pure acrylic acid, so an exploration into how the DES affected frontal polymerization was performed. The hydrogen bond acceptor of the DES was replaced by several analogs to determine the effect on the DES front behavior. None of the methacrylic acid-analog systems were able to sustain a front. While the acrylic acid-analog systems did sustain a front (with the exception of stearic acid), none of the fronts replicated the acrylic acid DES behavior. We propose that the reactivity of the acrylic acid and methacrylic acid is enhanced in the DES, and this was further explored by infrared spectroscopy.
