摘要: A phosphorus-containing amine, bis(4-aminophenoxy)phenyl phosphine oxide (BAPP), suitable for curing epoxy resins with improved fire performance was synthesized and characterized Fourier transform infrared spectroscopy nuclear magnetic resonance. The reactivity of the amino group evaluated by differential scanning calorimetry epoxy–amine mixture proton resonance unit. With BAPP as a agent, range high-functionality, aerospace were cured, dynamic kinetic parameters calculated from Kissinger's Ozawa's models compared those more widely used amines. thermal degradation properties studied thermogravimetric analysis, activation energy calculated, multistep process observed. © 2004 Wiley Periodicals, Inc.
