Chen, Xinggang;Cai, Yanqing;Qu, Xiongwei;Chen, Jun;Zheng, De research published 《 Preparation of a self-catalyzed amino-epoxy phthalonitrile resin with a large processing window》, the research content is summarized as follows. To expand the processing window of phthalonitrile resins, a novel self-catalyzed amino-epoxy 4-aminophenoxy phthalonitrile-resorcinol diglycidyl ether phthalonitrile (APRE-PN) resin was prepared via a two-step method of reacting amino and epoxy groups at a low temperature and then reacting nitrile with nitrile groups at a high temperature The amine-epoxy, epoxy-nitrile, and nitrile-nitrile reactions were confirmed by Fourier-transform IR spectroscopy and differential scanning calorimetry, and the probable polymerization mechanism was elucidated. The significant decrease in the m.p. of the proposed APRE-PN prepolymers dramatically expands the processing window (173°C) for an entire class of phthalonitrile matrixes. The APRE-PN resin exhibits excellent thermal stability and dynamic mech. properties owing to the presence of triazine, phthalocyanine, and oxazoline structures. The improved preparation method provides a new path for the preparation of phthalonitrile resins with large processing windows and new opportunities for the use of this type of thermosetting matrix in manufacturing various composite materials and prepregs.

4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., Name: 4-Nitrophthalonitrile
