Zusammenfassung:	An improved process is provided for the bromination of isoolefin-conjugated diolefin polymers by brominating said polymer in solution in selected halogen-containing hydrocarbons as solvent. There is also provided an improved product of said process wherein the brominated polymer contains not less than 80 per cent of the bound bromine atoms in a form suitable to participate in the vulcanization of the polymer and wherein not less than 70 per cent of the bound conjugated diolefin units are similarly so brominated.
