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: a) Production of prepolymer beads through a first suspension polymerization reaction using an aqueous suspension comprising styrene monomers and comprising particulate additives, b) isolation of the prepolymer beads, c) optional division of the prepolymer beads into fractions of different particle size and selection of one or more fractions for subsequent stages, d) production of an aqueous suspension of the prepolymer beads and conduct of a second suspension polymerization reaction in the presence of blowing agent and with addition of further monomers.
