Brominated syndiotactic polystyrene and the use thereof

摘要

The present invention provides a method of producing a flame-retardant polymer comprising mixing one or more polymeric base resins with a source of brominated syndiotactic polystyrene that displays a noncrystalline order and is produced by a process comprising brominating syndiotactic polystyrene in an inert reaction medium that is incapable of dissolving to any appreciable degree syndiotactic polystyrene at ambient temperature and pressure. The produced brominated syndiotactic polystyrene has a melting temperature in excess of about 325 DEG C.
