Analysis of polymers containing brominated diphenyl ethers as flame retardants after molding under various conditions

Three commercial plastic formulations (HIPS, ABS, and PBT) containing brominated diphenyl ethers as flame retardants were used to mold test samples under normal and abusive conditions. The samples were then analyzed for PBDDs and PBDFs. Under normal conditions, 2,3,7,8-brominated PBDDs and PBDFs were not detected.
