Abstract of the Disclosure A process is disclosed for polybrominating bisphenoxyalkanes without cleaving either phenoxy-to-alkylene linkage, characterized by reacting a bisphenoxyalkane having two or three carbon atoms in the alkane moiety with a stoichiometric excess of bromine chloride in the presence of a Lewis acid cat- alyst and a chemically inert organic solvent adapted to dissolve all of such compounds. Optionally, the bisphenoxyalkane and resulting product of the pro- cess may have alkyl and chlorine substituents in either or both phenyl groups.
