Wang, Ting;Wang, Zi-long;Dayo, Abdul Qadeer;Shi, Cheng-yu;Liu, Hui-bo;Pan, Zhong-cheng;Gorar, Athar Ali Khan;Wang, Jun;Zhou, Heng;Liu, Wen-bin research published 《 Synthesis and properties of a novel autocatalytic phthalonitrile monomer and its copolymerization with multi-functional fluorene-based benzoxazine monomers》, the research content is summarized as follows. A novel autocatalytic phthalonitrile monomer [4,4′-(((((oxy-bis [4,1-phenylene]) bis (azanediyl)) bis (methylene)) bis (2-methoxy-4,1-phenylene)) bis (oxy)) diphthalonitrile, OPD] is obtained by nucleophilic substitution of 4-nitro-phthalonitrile and bisphenol compound [4,4′-(((oxy bis [4,1-phenylene]) bis (azanylylidene)) bis (methanylylidene)) bis (2-methoxyphenol)]. Bisphenol compound is a reductant with secondary amine groups of Schiff base derived from the reaction of vanillin and 4,4′-diaminodiphenylether. The OPD monomer has a self-catalytic polymerizing reaction. OPD monomer has good processability, and the processing window was 130°C. Moreover, OPD polymer [poly(OPD)] shows higher glass-transition temperature (345°C). The 5% and 10% thermal decomposition temperatures of poly(OPD) and char yield at 800°C are 407, 451°C, and 69%, resp. To further improve the properties of poly(OPD), the OPD monomer was modified by multi-functional fluorene-based benzoxazine monomers (MFFB) due to their excellent reaction activities. The results showed that OPD/MFFB systems had high reaction activities. The similar thermal stabilities between OPD and MFFB can give stable and excellent thermal stability to the poly(OPD/MFFB). Compared with poly(OPD), the Tg values of poly(OPD/MFFB) were significantly increased, and their stiffness values were reduced. The tensile, flexural, and impact properties for poly(OPD/MFFB) were improved significantly.
Category: nitriles-buliding-blocks, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
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., 31643-49-9.
