Abstract: This invention relates to a method of preparing a brominated elastomer having a stabilized Mooney viscosity. The method includes polymerizing isomonoolefins and at least one polymerizable unit to obtain an elastomer/polymer; brominating the elastomer/polymer to form a brominated elastomer effluent; neutralizing the brominated elastomer effluent to form a neutralized effluent; volatizing off the hydrocarbon solvent; and recovering a brominated elastomer. In at least one point of the process, preferably prior to any significant temperature change in the brominated polymer, a Mooney stabilizer is added into the system. Portions of the Mooney stabilizer may be added at multiple points into the process.

Abstract: This invention relates to a brominated elastomer composition comprising a free radical scavenger. The scavenger is present in the amount of at least about 0.05 wt % of the composition. The scavenger is added to the composition so that the Mooney viscosity of the composition does not increase by more than about 15% to about 40%, for up to about 15 days at 80° C. The scavenger can be a sterically hindered nitroxyl ether, a nitroxyl radical, or both.
