Abstract
Polyphosphates had been used as thermal stabilizers for polyvinylchloride (PVC). The thermal stability of PVC films stabilized with polyphosphates was verified by using weight loss method, Fourier transform infrared (FTIR) spectroscopy, thermal aging test, optical microscope and atomic force microscope. The outcomes demonstrated that mixing of polyphosphates with PVC can obviously enhance the stability time of PVC and improve the initial color of it. Furthermore, polyphosphates could considerably decrease the concentrations of forming double bonds within the PVC chemical structure and decrease weight loss. In addition, polyphosphate has an excellent ability to reduce the releasing of hydrochloric acid (HCl) molecules. Hence polyphosphates can replace the labile chlorine atoms within the chemical structure of PVC chains.
