| Abstract: | A low molecular weight brominated polystyrene is prepared based on low molecular weight and small polydispersity polystyrene. The affect of broming agent amount on bromineconfent in brominated polystyrene was studied. The solubility of the catalyst was improved by mixed solvents. A high brominated polysty rene was prepared. The thermal stabilization of bromated polystyrene was tested by TGA. |

| Keywords: | low molecular weight bromated polystyrene cosolvent high bromine content |
