A technique capable of simultaneously monitoring bromide ions and an asso ciated weight loss of organic bromides when heated with an infrared heater chosen to reflect conditions similar to those encountered in the burning pro cess is described. The technique has been applied to a range of aliphatic and aromatic bromine compounds in order to evaluate their potential as candidate gas-phase combustion inhibitors for poly/ethylene terephthalate).

AbstractPoly(ethylene terephthalate) (PET) has been compounded with lignin (L) by a single-screw extruder. The influence of L presence and its content on the thermal stability of PET has been studied by using thermogravimetric analysis. The experiments carried out in oxidative conditions evidenced the barrier effect of L that interferes to the diffusion of the volatile degradation products to the gas phase and at the same time to the diffusion of the oxygen from the gas phase to the PET matrix. The influence of L on the melting behaviour of PET has been investigated on samples submitted to subsequent annealing steps procedure. X-ray techniques were employed to investigate crystallinity and crystal dimensions of pure PET and PET/L composites. Considering the supermolecular and crystal structure of the annealed samples, their melting behaviour was explained assuming small changes in the melting entropy.
