Abstract
Abstract The effect of bisphenol A bis(diphenyl phosphate) oligomer (BDP), a commercially available flame-retardant additive, on the limiting oxygen index test method and thermal decomposition of poly(butylene terephthalate) (PBT) was studied. The occurrence of an interaction between BDP and PBT was elucidated by TGA data, FT-IR study of solid pyrolysis products and GC/MS study of high boiling and gaseous pyrolysis products. BDP affects the mechanism of degradation of PBT and modifies the final structure of the residue. As a result, decomposition products of BDP partially becomes trapped in the residue, whereas triphenyl phosphate, diphenyl(isopropylphenyl) phosphate, phenol and alkylphenols evolve in the gas phase.
