| Abstract: | Cyanate ester（CE） was modified by two different modifiers,respectively.The DSC curves of the above two systems at different rates of heating were obtained.Furthermore,the curing kinetics was studied by using the Kissinger equation.The apparent activation energy,pre-exponential factor,reaction order and reaction rate constant at a temperature of 135℃ for the bisphenol A/CE were 68.98kJ·mol-1,1.27×108min-1,1.10 and 0.1889min-1 by calculation;for the bisphenol M/CE,they were 64.58kJ·mol-1,3.51×107min-1,1.11 and 0.1905min-1,respectively.The data illustrated that increasing the flexibility of reactant was benefit to accelerate the reaction. |
