【Abstract】 The thermosetting reaction of the epoxy resin/tung oil acid anhydride/neodymium acetylacetonate(AD) system was studied. The time to gelation and the apparent activation energy for the reaction were determined by DSC, TBA and the cure test. The kinetic parameters were obtained. The results show that AD appears to be a latent accelerator for the anhydride-cured epoxy resin system.更多还原
