Abstract
Four current commercial antioxidants (Naugard 445, Ethanox 330, Irgano x 1098 and a blend of Irganox 1098 and 1019) were added during synthes is of poly(ethylene terephthalate) in order to test their thermo-oxida tive stability and eventually to obtain more thermostable products dur ing synthesis and processing. Their stabilization effect was evaluated by DSC analysis in nitrogen and air, using as criteria the stabilizat ion coefficient and the induction period of oxidation. At low concentr ations (0.03% and 0.10%), under the conditions used, better results we re obtained with Naugard 445 and Ethanox 330, while at higher concentr ations (0.5% and 1.0%) Irganox 1098 and the blend of Irganox 1098 and 1019 were better than the others.
