Monitoring of the degree of curing of phthalonitrile high temperature resinby FT-IR spectroscopy

In this work, a new curing cycle with amine curing agents (methylene dianiline) was proposed forthe bisphenolA-based phthalonitrile resin (BAph). The amount of cyanide group reaction during thecuring process was measured by FTIR spectroscopy as an indication for resin curing percentage.FTIR Spectroscopy showed that the mechanism of phthalonitrile resin curing is combined formationof polyisoindoline, triazine ring, and phthalocyanine structures
