dc.descriptionMatrix-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. (C) 2009 Elsevier Ltd. All rights reserved.
