Oligoimide containing propargyl and phthalonitrile groups in one mol. (OI-PR-PN) was synthesized by a facile and eco-friendly method in benzoic acid melt. To incorporate side propargyl groups into the polyimide backbone, a new monomer was developed – 5-(2-propyn-1-yloxy) benzene-1,3-diamine (PBD). The OI-PR-PN dual-curing behavior was studied by DSC and FT-IR methods. The curing of phthalonitrile groups can be promoted by the intermediates formed during the propargyl groups polymerization This allows crosslinking of phthalonitrile groups at 300-350°C in one component system. OI-PR-PN showed good solubility in low b.p. solvents and had low melt viscosity (up to 8 Pas at 250°C). The temperatures of 10% weight loss of the cross-linked OI-PR-PN and oligoimide containing only propargyl groups (OI-PR) are 496°C and 450°C correspondingly. The completely cured OI-PR-PN glass transition temperature measured by dynamic mech. anal. was 424°C with a storage modulus 4.2 GPa at 50°C. The possibility of crosslinking without using curing additives with a combination of excellent thermal and mech. properties indicates the potential of OI-PR-PN as a matrix for composite manufacturing
31643-49-9, 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., Electric Literature of 31643-49-9
