Investigating the Catalytic Effect of 2-Isopropylimidazole on Polyurethane Synthesis Abstract: Polyurethane (PU) is a versatile polymer with a wide range of applications. The synthesis of PU typically involves the reaction between isocyanates and polyols, often requiring catalysts to accelerate the reaction rate and tailor the product properties. This study investigates the catalytic effect of 2-isopropylimidazole...
