The effort to minimize the formation of brominated hydrocarbons has been conducted by temperaturecontrol during pyrolysis of high impact polystyrene containing decabromodiphenyl ethane (HIPS-Br) in presence of polyethyelene (PE)/polypropylene (PP)/polystyrene (PS). The products were analyzed with different gas chromatographs equipped with TCD, FID, MSD, and ECD. The controlled pyrolysis of PE/PP/PS/HIPS-Br showed that there are significant differences in the yields and composition of pyrolysis products. By controlling the temperature of pyrolysis, the formation of brominated hydrocarbons can be minimized.
