Bestimmung von bromierten Dibenzofuranen, die bei der Thermolyse von Polymeren mit Decabromdiphenylether als Flammschutzmittel gebildet werden.
Determination of brominated dibenzofurans formed by thermolysis of polymers containing decabromodiphenylether as flame retardant.
Fresenius Z. Anal. Chem. 327, 297-300 (1987)
Several plastics (polyester and hardened epoxideresins) with flame retardants as additives were tested for the formation of brominated dibenzofurans and dibenzodioxins under temperatures from 400 °C to 800 °C under aerobic conditions. 2,3,7,8-Tetrabromodibenzodioxin was not formed at a detection limit of 10 ppm (μg·g-1). At 400 °C, polymers containing decabromodiphenylether and antimony trioxide as flame retardant yield up to 4,000 ppm tetrabromodibenzofurans (TBrDF), besides other brominated dibenzofurans. In contrast, formation of polybrominated dibenzofurans does not occur with polymers containing decabromodiphenylether without antimony trioxide. 2,3,7,8-Tetrabromodibenzufuran could not be found at a detection limit of 20 ppm. Under the given thermolytical conditions, polymers with brominated flame retardants such as tetrabromobisphenol-A, polytribromostyrene, hydroxyethylated tetrabromobenzimidazolone, poly(pentabromobenzyl)acrylate or N,N′-ethylene-bis-tetrabromophthalimide snowed no tendency to form polybrominated dibenzodioxins or dibenzofurans, even in the presence of antimony trioxide.
