The Influence of 2-Phenylimidazole on the Glass Transition Temperature of Epoxy Polymers Abstract: This article investigates the influence of 2-phenylimidazole (2-PI) on the glass transition temperature (Tg) of epoxy polymers. Epoxy resins are widely employed in diverse applications due to their excellent mechanical properties, chemical resistance, and electrical insulation. The glass transition temperature is a...
