Synthesis and Investigation of the Properties of a Branched Phthalonitrile Containing Cyclotriphosphazene

To study the properties of cyclotriphosphazene (CTP)-containing phthalonitriles, a branched phthalonitrile containing CTP (CTP-PN) with self-catalytic behavior was designed and synthesized. The structure of CTP-PN was characterized by FT-IR (Fourier transform infrared spectroscopy), MS (mass spectroscopy),
