Abstract
A series of imidazole (MI) blocked 2,4-toluene diisocyanate (TDI) with polyethylene glycol (PEG-400) as soft segment (PEG-MI-b-TDI) were synthesized for toughening and curing the bisphenol A type epoxy resin (E-44). Fourier transform infrared (FTIR) spectrum indicates that the NCO groups of the isocyanate molecule are blocked with MI. For curing epoxy systems, elimination of epoxy group and the formation of urethane bonds were studied by FTIR...
