1-Isobutyl-2-Methylimidazole: A Promising Catalyst for Polyurethane Synthesis Abstract: Polyurethane (PU) materials, prized for their versatility and wide-ranging applications, rely heavily on effective catalysis for their synthesis. Traditional catalysts, such as tertiary amines and organotin compounds, have faced increasing scrutiny due to environmental and health concerns. This has fueled the search for alternative catalysts with improved...
