15. Thermal degradation pathways of PBT have been elucidated by thermal volatilization analysis and related techniques. The authors postulated that the thiazole linkages of PBT undergo rearrangement and some fragmentations in overlapping and competing processes to expel heteroatoms and condense the aromatic rings into a carbonaceous char.
