Abstract: Brominated vinylaromatic-diene block copolymers (Br-SBC) comprising a vinylaromatic polymer block S and a brominated diene polymer block BB, wherein before bromination the weight-average molar mass Mw of the block S is greater than or equal to Mw of the block BB, use thereof as flame retardants, and also polymer compositions comprising these for unfoamed and foamed thermoplastic polymers, for example EPS and XPS.

Abstract: Expandable styrene polymers comprising polymeric brominated flame-retardant, wherein the polymeric brominated flame-retardant comprises at least one brominated polybutadiene block having a bromination degree between 33 and 75%, based on the double bonds in the polybutadiene block before bromination, a process for producing such expandable styrene polymers by suspension polymerization and particulate foam moldings made therefrom.
