The Name is 3-Nitrobenzaldehyde. Through research, I have a further understanding and discovery of 99-61-6.
To get better processability and preparing process of Poly (ethylene terephthalate) polymer, -NO2 was used to modify Schiff Base to synthesize a novel flame retardant monomer of 5-([3-nitrobenzylidene] amino) isophthalic acid (BNA) to prepare flame retardant and anti-dripping PET copolyester (BNA(n)PETs), where the electron effect of -NO2 passivate the cross-linking reactivity of BNA in BNA(n)PETs to enhance its cross-linking temperature to improve its processing zone with better processability. The results demonstrated that the cross-linking temperature of BNA(n)PETs was improved from the range of (250-348 degrees C) to (355-385 degrees C), and BNA accelerated the reaction of the polycondensation of PET for saving time of 42%. -NO2 enhanced the residue char of BNA(n)PETs in high temperature and further improved its flame retardancy. BNA(10)PET with 7.2 mol% of BNA had LOI of 31.8% and V-0 of UL-94 without drip, and the introduction of -NO2 did not change the flame retardant mechanism in BNA(n)PETs.
