Comment on “Degradation of the Polymeric Brominated Flame Retardant “Polymeric FR” by Heat and UV Exposure”

Retardant “Polymeric FR” by Heat and UV Exposure” K et al. recently published on the degradation of a polymeric brominated flame retardant, “Polymeric FR”, under thermal and UV exposure conditions. This work intended to explore the long-term behavior of Polymeric FR when used in polystyrene (PS) insulation foam applications and evaluate potential degradants formed when used in these applications. As part of a series of studies on the Polymeric FR substance, the authors have correctly noted the limitations of their research to the actual degradation profile of the Polymeric FR technology as applied in practice, most notably
