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.

Abstract: Brominated styrene-butadiene copolymers are useful gas transport films. The gas transport films are made by brominating a starting styrene-butadiene copolymer, and then forming the brominated styrene-butadiene copolymer into a film The film may contain a blend of the brominated styrene-butadiene copolymer with one or more other polymers. The films have excellent selectivities between certain pairs of gasses, and exhibit high gas transport rates for various gasses such as carbon dioxide and water vapor.

Abstract: Conjugated diene polymers such as a styrene-butadiene copolymer are sequentially brominated by reaction with a quaternary ammonium tribromide or quaternary phosphonium tribromide and halohydrated by reaction with an N-haloimide compound. This produces a brominated and halohydrated polymer with very good thermal stability. The product is useful as a flame retardant in a variety of polymer systems.

Abstract: Aliphatic bromine-containing polymers are stabilized using a mixture of an alkyl phosphite and an epoxy compound. This stabilizer package is very effective at preventing cross-linking reactions from occurring when the aliphatic bromine-containing polymer is subjected to high temperatures as are seen in melt processing operations. The stabilized aliphatic bromine-containing polymer is useful as a flame retardant for other polymers, notably polystyrene foam.
