    摘要: Tribromostyrene (TBS) is produced by the preparation of a TBS precursor, which is .beta.-bromoethyl-tribromobenzene (.beta.-BrBr.sub.3), and the successive elimination of hydrogen bromide from said precursor. The precursor is prepared by selective bromination of phenethyl bromide (.beta.-Br), wherein the molar ratio of bromine to phenethyl bromide is comprised between 2.5 and 3.5, and preferably between 3.1 and 3.3 included; and by adding bromine, after an initial addition, at a controlled molar rate.

    摘要: Novel formulations comprising pentabromobenzylbromide (PBBBr) and a carrier, for use as a flame retardant for application on a substrate, and processes for their preparation are disclosed. Further disclosed are articles-of-manufacture having these formulations applied thereon, and the use of PBBBr as a flame retardant for application on a substrate. These novel formulations are particularly effective as flame retardants for textiles, and are characterized by a low add-on and a high washing fastness.
