2-Isopropylimidazole: A Novel Co-Catalyst in Polyurethane Elastomer Syntheses Abstract: Polyurethane elastomers (PUEs) are versatile materials with a wide array of applications. The synthesis of PUEs typically involves the reaction of polyols and isocyanates, often requiring catalysts to accelerate the reaction and control the properties of the resulting polymer. This article explores the use of 2-isopropylimidazole...
