Abstract: A new phthalocyanine cyano bisphenol compound PPCN was synthesized by
nucleophilic substitution reaction with phenolphthalein (PP) and
2,6-dichlorobenzonitrile as raw material and then reacts with
epichlorohydrin to synthesize phthalocyanine cyano group epoxy resin.
The structure of the target product is verified by 1H-NMR spectroscopy
and Fourier transform infrared spectroscopy (FTIR). The curing
performance and kinetics of PPCE/methyl nadic anhydride (MNA) were
investigated by DSC. The apparent activation energy evaluated according
to Kissinger model is 57.78 kJ/mol, and the calculated reaction order is
0.76 based on Crane method. The results of the DMA and TGA show that the
cured resin possesses excellent thermos-stability with a glass
transition temperature 179℃ for the completely cured resin, and the
activation energy of the thermos-degradation process is 52.88 kJ/mol and
13.21 kJ/mol for temperature ranges 327℃~357℃ and 357℃~574℃
respectively.
