BROMINATED STYRENIC POLYMER AND THEIR PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide brominated styrenic polymers useful for flame retardants for thermoplastic polymers.

SOLUTION: The brominated anionic styrenic polymer has an initial Hunter Solution ΔE value in the range up to 1.50. The brominated anionic styrenic polymer further has better melt flow and/or lower initial Hunter Solution ΔE value than the best previously-known brominated anionic styrenic polymers. Other features of the polymer includes high thermal stability at 320°C and/or an extremely low initial color value.
