Recycling PU Foams Using Residual Polymerization Catalysts
Lily Felsenthal and Subeen Kim recently published a paper in JACS demonstrating that commercial polyurethane (PU) foams containing residual polymerization catalysts can be reprocessed into films without any additional catalysts. Residual tertiary amine catalysts in PU foam enabled reprocessing PU foam into film as covalent adaptable networks, supported by model studies showing their carbamate exchange capacity and mechanism.…
