摘要：
Brominated butadiene polymers are recovered from a bromination reaction solution by partially stripping the solvent to form a concentrated solution or slurry, and then recovering the brominated butadiene polymer from the concentrated solution or slurry. The process allows for a simplified, effective an economical recovery of the brominated butadiene polymer. Brominated butadiene polymers recovered in this manner are often very thermally stable.
