“…In our earlier studies, we examined the temperature influence on the composition and concentrations of the volatile substances emitted during the thermal degradation of PET in air. 26 This article reports the results of our studies on the composition and amounts of the volatile substances evolved from PET during thermal degradation in nitrogen at several different temperatures for 20 min. The aim of this work was to identify and quantify the substances evolved and to examine the temperature effect on both the amount and type of compounds formed.…”

“…In a study of poly(ethylene terephthalate) (PET) granules, acetaldehyde and formaldehyde were shown to be emitted following thermal degradation at 200-300°C, with a wider range of VOCs detected after degradation at higher temperatures (Dzieciol & Trzeszczynski, 1998). Mixtures of low-molecular weight compounds extracted from samples of commercial rubber were shown by GC-MS analysis to contain small hydrocarbon fragments -evidence of polymer chain scission (Delaunay-Bertoncini et al, 2004).…”

There is an acknowledged need for improved conservation of plastic and rubber objects within collections, including improved methods of condition assessment, material identification, and better understanding of material degradation. This reflects the inherent instability and wide-ranging formulations of many such objects and also the relative lack of knowledge in this field. Analysis of volatile organic compounds (VOCs) is a useful method for understanding the chemical processes involved in polymer degradation and for the identification of materials. Conservators and curators have used odor analysis to identify historical plastics for many years, and techniques ranging from acid detection strips to laboratory-based techniques such as solid-phase microextraction-gas chromatography-mass spectrometry have been used to characterize plastic and rubber materials and to understand their degradation. VOC analysis also has potential as a technique for bulk material identification, as a complementary tool to spectroscopic analysis of the surface. A significant advantage of VOC analysis is its potential to be non-invasive, avoiding destructive sampling or even contact with an object. However, there is a greater potential for VOC analysis to be of benefit within conservation than is currently being exploited and significant scope for future research. In fields such as construction or waste management, there is also significant research into analysis of VOC emissions from plastic and rubber materials. The goal of this paper is to systematically review research from a range of fields including conservation, polymer degradation, and plastics recycling and it includes the use of VOC analysis to understand the causes of damage to plastic and rubber objects, to provide evidence of degradation and to monitor degradation progress, and to identify materials and distinguish between different formulations. Summaries of relevant studies are given, and volatile markers of object damage and polymer degradation and key volatile identifiers of a particular material are highlighted.

“…The temperature was selected because of the thermal analysis showed that it assures complete decomposition of polyethylene when the maximum amounts of products are formed. Amounts of particular products collected were recalculated to determine the yield from 1 g PE [12,13]. Percentage shares of particular components of the PE decomposition products are specified in Table 1.…”

Abstract. Thermal analyses (TGA and DTA) of the composite, comprised of 10% polyethylene (PE) scrap and 90% copper ore concentrate, enabled determination of the temperature range and decomposition degree of the organic matters in argon atmosphere. Products of pyrolysis were qualitatively and quantitatively determined. The results were compared to those obtained for products of pyrolysis of the composite in air. Products of pyrolysis were identified by means of the gas chromatography (GC) method alone or supported with results of mass spectrometry analyses (GC-MS).
