N,N'-alkylene-bis-tetrahalophthalimides, such as N,N'-ethylene-bis-tetrabromophthalimide, are prepared by reacting about two molar proportions of a tetrahalophthalic anhydride, such as tetrabromophthalic anhydride, with one molar proportion of a diaminoalkane containing 2-6 carbon atoms, such as 1,2-diaminoethane, in an aqueous medium. |
