Abstract

The curing reaction kinetic of bisphenol A cyanate ester resin modified by phenolic epoxy was studied by differential scanning calorimetry(DSC).According to Kissinger equation the apparent activation energy was 60.81kJ/mol.The reaction order was 0.8846 with Crane theory.The initial temperature,peaking temperature and terminal temperature of the modified cyanate resin in the cure process was 120.00℃,176.67℃ and 226.67℃ respectively.A suitable cure processing for the copolymer was obtained with DSC and rheological properties,furthermore mechanical properties were tested to prove the cure processing was suitable.
