  • Publication number: 20070197112
    Abstract: 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.

  • Publication number: 20050075442
    Abstract: A fire retarded polymer composition is disclosed, which comprises a polymer component, at least one halogen-containing fire retardant and a heat expandable graphite. The polymer component is selected from among polystyrenes, polyesters and polyolefins. The halogen of the fire retardant is bromine or chlorine, and the total amount of the fire retardant and the heat expandable graphite is from about 6.5 to about 40% by weight. The composition may also contain a metal oxide fire retardant, such as antimony trioxide, but if so, it contains it in amounts much lower than those required in prior art compositions to achieve the same degree of fire retardancy. It is preferred that the heat expandable graphite be such as to expand 50 times or more on shock heating from room temperature to 900° C. The process by which the expandable graphite is produced is not critical, and it is known, for example, to produce it by oxidation of natural or artificial graphite.

  • Patent number: 4835326
    Abstract: The invention relates to the stabilization of monobromostyrene of dibromostyrene and of mixtures of these. The stabilization is effected by means of hydroxy-benzene derivatives, where the benzene ring contains at least two substituents, one of these being a hydroxy group. The process is advantageously carried out by heating the styrene material with an excess of the inhibitor, distilling the monomer and adding an additional quantity of the inhibitor. The distilled monomer is preferably dried prior to the addition of the further quantity of inhibitor.
