摘要：
Many chemical changes have been made to poly(vinyl chloride) (PVC) in order to enhance its photo-stability features, the use of PVC in new applications, and the study of PVC-related phenomena. The chemical modification of PVC using captopril as a modifying agent is described in this paper. Infrared spectroscopy and energy dispersive X-ray analysis was used to characterize the modified polymer. Metal salts (HgCl2, CoCl2, ZnCl2, NiCl2, and CdCl2) were used to react with the modified film and form polymeric complexes. FTIR, weight loss percentage, AFM, EDX, and SEM approaches were used to analyze polymeric films that had been exposed to UV radiation for 300 hrs. The modified PVC complexes films have shown excellent stability against photo-degradation even after 300 h of irradiation by UV light. Thermogravimetry (TGA) was used to evaluate the thermal characteristics of the modified polymers, which demonstrated that the synthesized polymer complexation showed good thermal stability. © 2022
