| description | An improved process is provided for the bromination of isoolefin conjugated diolefin polymers by brominating said polymer in solution in a solvent comprising a mixture of an inert saturated paraffinic hydrocarbon and an inert halogen-containing hydrocarbon. There is also provided an improved product of said process wherein the brominated polymer contains not less than 70 percent of the bound conjugated diolefin units which are brominated and also not less than 80 percent of the bound bromine atoms are in a form suitable to participate in the vulcanization of said polymer. |
