Abstract
Catalyst-free synthesis in three kinds of isocyanate-blocked imidazole compound was successfully achieved by chemically connecting 2-ethyl-4-methylimidazole (2E4MI) with hexamethylene diisocyanate (HDI), trimethylhexamethylene diisocyanate (TMHDI) or 4,4′-diphenylmethane diisocyanate (MDI), which were tested as the latent hardeners for epoxy (EP) resins. The chemical structures of the synthesized HDI-2E4MI, TMHDI-2E4MI and MDI-2E4MI were...
