Supervisor: Véronique Coma and Étienne Grau During my PhD, I focused on understanding the formation of Non-Intentionally Added Substances (NIASs) in polypropylene (PP)-based plastic materials throughout their preparation, recycling, and aging processes (including UV and thermal aging). The goal of PhD project was to identify and quantify these substances effectively. The research primarily involved identifying the main additives used in PP, determining the optimal extraction solvents and methods, and establishing the most suitable extrusion conditions for blends consistent with those used by major plastics manufacturers. I developed analytical methods utilizing techniques such as GC-FID, GC-MS, NMR, and FTIR to identify the chemical structures of NIASs and quantify their presence. To understand the impact of NIAS on PP, I also studied the physical properties of PP using SEC, TGA, and DSC. In the subsequent phase, I applied these improved methods to the analysis of recycled and aged PP to investigate how NIASs evolved during these processes.
