Synthesis of Brominated Polystyrene with Bromine Chloride

Abstract The optimal parameters of synthesizing brominated polystyrene(BPS) was determined in the presence of antimony chloride as a Lewis acid,bromine chloride and polystyrene as raw materials.The effects of the amount of catalyst and reaction temperature in the synthesizing process on the bromine content of product have been studied.Product qualities including bromine content and whiteness(W_b) have been examined.The results show that when the amount of catalyst is 3%��15% and the reaction temperature is 10��(30 ��),the bromine content could be above 65%,whiteness(W_b) could be above 70.Ideal thermo stability and infrared spectrum were measured.The results of thermogravimetric and FTIR analysis show that the products have ideal thermo-stability and high quality.In addition,the optimal synthesizing parameters mentioned above were verified in a way of continuous and stable operation for kilo-scale process of synthesizing BPS.
