Item Data from: Controlled Anionic Polymerization Mediated by Carbon DioxideJacky, Paige; Easley, Alexandra; Fors, Brett (2025)These files contain data supporting all results reported in Jacky et. al. Controlled Anionic Polymerization Mediated by Carbon Dioxide. In Jacky et. al. Controlled Anionic Polymerization Mediated by Carbon Dioxide we found: Anionic polymerizations of vinyl monomers are a powerful synthetic platform to make well-defined materials. However, these reactions are extremely sensitive to moisture and oxygen, require the use of highly purified reagents, must be run at low temperatures, and use hazardous and difficult-to-handle alkyl lithium initiators. Together, these drawbacks limit the practicality of these polymerizations and impede their widespread usage. On this basis, the development of a user-friendly anionic polymerization process for methacrylates is a grand challenge. Herein, we report an anionic polymerization of methacrylates mediated by CO2 that can be run at elevated temperatures and allows the use of an easy-to-handle solid initiator. The reversible addition of CO2 to the enolate chain-end efficiently tempers the reactivity of the anion, giving polymers with narrow molar mass distributions and excellent molecular weight targeting at elevated temperatures. Our scalable and more user-friendly CO2-mediated method improves the accessibility and safety of anionic polymerizations and facilitates the production of a variety of polymeric materials.Item Data from: Degradable Thermosets via Orthogonal Polymerizations of a Single Monomer DatasetDreiling, Reagan J.; Huynh, Kathleen; Fors, Brett P. (2024)These files contain data supporting all results reported in Dreiling, R. J. et al. Degradable Thermosets via Orthogonal Polymerizations of a Single Monomer. In Dreiling, R. J. et al we found: Crosslinked thermosets are highly durable materials, but overcoming their petrochemical origins and inability to be recycled poses a grand challenge. Many strategies to access crosslinked polymers that are bioderived or degradable-by-design have been proposed, but they require multiple resource intensive synthesis and purification steps and are not yet feasible alternatives to conventional consumer materials. Here, we present a modular, one-pot synthesis of degradable thermosets from the commercially available, biosourced monomer 2,3-dihydrofuran (DHF). In the presence of a Ru catalyst and photoacid generator, DHF undergoes slow ring-opening metathesis polymerization to give a soft polymer; then, exposure to light triggers strong acid generation and promotes the cationic polymerization of the same DHF monomer to spatially crosslink and strengthen the material. By manipulating catalyst loading and light exposure, we can access materials with physical properties spanning orders of magnitude and achieve spatially resolved material domains. Importantly, the DHF-based thermosets undergo stimuli-selective degradation and can be recycled to monomer under mild heating. The use of two distinct polymerization mechanisms on a single functional group allows the synthesis of degradable and recyclable thermoset materials with precisely controlled properties.Item Compound data for Selective Electrocatalytic Degradation of Ether-Containing PolymersHsu, Jesse H.; Ball, Tyler E.; Oh, Sewon; Stache, Erin E.; Fors, Brett P.
