Influences of Chemical Alterations on Thermostabilization and Morphology of PVC-co-Schiff Base Microspheres.

This study focuses on enhancing the thermal stability of Poly(vinyl chloride) (PVC) by introducing Schiff bases, aiming to mitigate thermal degradation. The investigation employs a comprehensive array of analysis techniques, including Fourier Transform Infrared Spectroscopy (FTIR), weight loss estimation, 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.
