Decabromodiphenyl oxide DBDPO

For the decabromodiphenyl oxide (DBDPO) pyrolysis reactions, two different procedures were used to synthesize the series of brominated diphenyl oxides and dibenozofurans employed as the relative retention time standards AlBr3/Br2 in ethylene dibromide and Fe° (metal)/Br2 in tetrachloroethylene. The rate of the initial bromination steps in the former reaction was so rapid that only the higher degree of bromination adducts could be isolated. The rate of the Fe°/Br2 reaction was found to be much slower, especially during the initial stages, and these reactions yielded a broader range of relative retention time reference peaks.

The effect of additives, others than plasticizers, on the dynamic mechanical properties of styrene polymers have attracted little attention from researchers. Flame retardants such as l,2-bis(tetrabromophthalimide)ethane, crystalline decabromodiphenyl oxide (DBDPO) and antimony trioxide (Sb203) do not affect the a relaxation of aPS [38,39]. 

Decabromodiphenyl oxide (DBDPO) is the most widely used flame retardant for HIPS, its low cost and high bromine content making it a popular choice. DBDPO has some solubility in polystyrene, but also acts as an insoluble filler. DBDPO will discolor on exposure to UV light, so it is usually used in painted or dark-colored parts. 

Bromine compounds are also used as fire retardants. These compounds are about twice as effective as chlorine compounds on a weight basis, so that significantly lower concentrations are needed. However, bromine compounds are higher in cost than chlorinated compounds and are generally less stable under exposure to heat and light (29). Those compounds containing aromatic bromine are significantly more stable to heat and hydrolysis than the aliphatic type. Examples are decabromodiphenyl oxide (DBDPO), tetrabromobisphenol and tetrabromobisphenol A. A pentabromodiphenyl oxide blend is available for urethane foams and polyesters (34). Aliphatic bromine-type additives are used as flame retardants in plastic foams (polyurethane and polystyrene (33). 

Brominated hydrocarbons. Brominated hydrocarbons represent the highest dollar volume among all flame retardants used worldwide. The major additive types are decabromodiphenyl oxide (DBDPO) and derivatives of tetrabromobisphenol A(TBA). The major reactive type is TBA itself. Significant amounts of TBA are also used to make additive types. Typically, brominated compoimds are used with a synergist...

Brominated and chlorinated FRs can also react synergistically with each other in plastics compounds. Occidental s proprietary chlorinated FR can be used with decabromodiphenyl oxide (DBDPO) to flame retard ABS, and mixtures of chlorinated and brominated FRs can be used in polyolefins. Work on ABS formulations suggests that the highest oxygen index is obtained at a 1 1 chlorine/bromine mixture, which also gives UL 94 V-0 rating at both 3.2mm and 1.6 mm,...
