LOW MOLECULAR WEIGHT BROMINATED POLYMERS AND THEIR USE IN THERMOPLASTIC FORMULATIONS

摘要

This invention relates flame retardant compositions containing low molecu lar weight brominated anionic, chain transfer, vinyl aromatic polymers, here inafter "ACTVAP". The compositions can accommodate high bromine content whil e still exhibiting a low thermally labile bromine content. The compositions have glass transition temperatures, Tg, that are predictive of acceptable me lt flows and heat distortion temperatures (HDT) in HIPS and ABS based formul ations substrates. The compositions, are suitable flame retardant candidates for use in thermoplastic formulations, e.g. polystyrene and ABS formulation s.
