Tetra Schiff Bases as Polyvinyl Chloride Thermal Stabilizers

Tetra Schiff bases were used as thermal stabilizers to enhance the properties of polyvinyl chloride (PVC) when operated at high temperatures. The stability PVC films doped with was tested by weight-loss method, Fourier transform infrared (FTIR) spectroscopy, aging test, optical microscope, and atomic force microscope (AFM). Results showed that embedding these additives increased time polymer, which decreased degradation reaction tendency. Furthermore, primary color improved adding using oven-aging. In addition, resulted in a significant reduction PVC’s conjugated double bonds and, hence, weight loss.
