The invention relates to a preparation method of brominated polystyrene, comprising three steps of catalyzing and brominating, neutralizing washing, and solidifying and separating. The step of catalyzing and brominating comprises the following steps: dissolving polystyrene into dichloroethane solvent, adding antimony trichloride catalyst into the solution, dropwise adding bromine chloride into ...

In the case of BDE-209, BDE-47 and BDE-99, there is evidence that lower brominated congeners are more toxic to living organisms than higher brominated congeners, but there is no information regarding other congeners like BDE-154. This evidence suggests that different PBDE structures can trigger human liver cell apoptosis by distinct mechanisms.
