Abstract
Brominated styrene-butadiene copolymers are recovered from solution in an organic solvent. The copolymer solution is mixed with a liquid non-solvent in the presence of a suspension stabilizer to form a dispersion. The dispersion is heated to vaporize the organic solvent. This process produces precipitated copolymer particles having useful particle sizes, which can be easily used in downstream applications.
