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.
