文摘The reaction mechanism, reactivities, and apparent activation energies of epoxy/dicyanamide curing system accelerated by C6H5NHCONR2 (R=CH3, n-C4H9, i-C3H7,) werestudied by DSC and GC techniques. The results showed that in reaction of C6H5,NHCONR2with either dicyanamide or epoxy resin there was a dimethylamine released reacting with epoxy resin, giving a tertiary amine, which accelerated the anionic homopolymerization of epoxy resin.
