Abstract

This study marks a positive stride towards the development of more stable and reliable PVC materials, with implications for diverse applications demanding superior thermal performance.And study focuses on enhancing the thermal stability of Poly(vinyl chloride) (PVC) through introducing Schiff bases, aiming to mitigate thermal degradation. The investigation employs a comprehensive array of characterization techniques, including Fourier Transform Infrared Spectroscopy (FTIR), weight loss analysis, and microscopy (optical, scanning electron, and atomic force) to assess the impact of the modifications. Oven-aging tests reveal notable improvements in color stability for modified PVC films. Results consistently indicate a prolonged color change process in modified PVC, signifying enhanced thermal stability. The modifications demonstrate a remarkable ability to neutralize HCl and passivate labile chlorine atoms; this contributes to elevated thermal resistance and effective prevention of thermal degradation in PVC. This study marks a positive stride towards the development of more stable and reliable PVC materials, with implications for diverse applications demanding superior thermal performance
