Mechanism of Brominated Epoxy Resin Degradation

Study results of brominated epoxy resin decomposition showed that the liquid products at three different temperatures (300 °C, 360 °C, 400 °C) mainly contained some complex organic compounds of 6-15 carbon atoms, which molecular weights ranged 

Based on analysis of products distribution [25], it was concluded that there were two kinds of decomposition action hydrolysis mainly at lower temperature and pyrolysis mainly at higher temperature. At low-temperature stage, the brominated epoxy resin was mainly decomposed into bisphenol A, brome-phenol, isopropyl phenol monomer, etc., while at high-temperature stage, the brominated epoxy resin was mainly decomposed into phenol, o-cresol, p-cresol, and other small molecule compormds without bromine.
