| Abstract: | This bachelor thesis depicts the chemical degradation of polyurethane and melamine formaldehyde, which are representatives of thermosets. A high–pressure reactor was used to perform chemical degradation. The effectiveness of the chemical degradation of the selected thermosets was monitored by measuring pH, total organic carbon (TOC) and total nitrogen (TN) of the liquid residues. The remaining solid material was characterized by infrared spectroscopy and the mass loss was determined. Using these analytical methods, it was concluded that the chemical degradation depends on the temperature and the duration of the reactions as well as the reaction medium. It was found that “white liquor” is a more effective medium for the chemical degradation of polyurethane and melamine formaldehyde than water. |
