Abstract

Microwave irradiation of high impact polystyrene (HIPS-Br) containing brominated flame retardant i.e., decabromodiphenyl ether (DDO) or decabromodiphenyl ethane (DDE) was performed using aqueous and organic solvents for the removal of bromine. The microwave irradiation of HIPS-Br with triethylene glycol (TEG; 20 ml) at 250 °C for 30 min was found to be suitable condition for the removal of bromine (85 wt%) from the plastic, enabling recovery of the bromine free plastics.
