WebMay 22, 2016 · Curing of diphthalonitrile resin was studied by IR spectroscopy, gel permeation chromatography, and differential scanning calorimetry. Polymerization of the resin yields triazine and phthalocyanine structures, but the main structural components of the cured matrix are polyimines/isoindolenines. Download to read the full article text. Majority of the research related to phthalonitrile systems is focused on two areas, that is, (1) design and synthesis of phthalonitrile-based monomers/oligomers containing a variety of linkages and groups and (2) investigations on a variety of curing agents to cut short their tedious cure schedule.
