Abstract
Matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) has been shown to provide a valuable technique to study the thermomechanical degradation of poly(ethylene terephthalate) (PET). MALDI-MS has been tested to monitor both the admixture of post-consumption bottle-grade PET (PET pc-btg) with virgin bottle-grade PET (PET v-btg) and the thermomechanical degradation effects on the chemical properties of PET v-btg. Principal component analysis of MALDI-MS data classify the samples into groups with specific features: a) PET-btg with intrinsic viscosities of 0.80 or 0.65–0.60 dL g −1); b) processed or virgin PET with the same intrinsic viscosity; c) PET v-btg from PET containing PET pc-btg; and d) PET v-btg from different manufacturers. MALDI-MS data is therefore able to reveal the quality of PET-btg resins preventing frauds and illegal use of recycled PET-btg.
