The objectives of this work are to investigate the cure behaviour and structure of bisphenol A dicyanate-novolac epoxy blends. The cure characteristics were investigated by gel time determination and dynamic DSC. To disclose the structural differences between cured cyanate-novolac epoxy blends and more traditional cyanate-diglycidyl ether systems, FTIR investigations were performed on the two kinds of blends, and in situ FTIR was used to examine the Bauer mechanism. The effects of epoxy concentration in the blend on the cure kinetics was investigated using two blends with different molar ratios, and in situ FTIR. 33 refs.
