摘要：

Biaxially stretched poly(ethylene terephthalate) foils, poly(ethylene terephthalate) and poly(styrene) spin coated films as well as self-supporting poly(bisphenol-A-carbonate) films were analysed by surface sensitive near edge X-ray absorption fine structure spectroscopy (NEXAFS) before and after low pressure oxygen DC plasma treatments. The degradation effects of the treatment are discussed in a common way in terms of probable reaction pathways. The results are, when possible, cross-checked by XPS. NEXAFS analysis provides data on the phenyl ring, ester and carbonate group degradation in a straightforward manner. It can be shown that the phenyl rings in partially crystalline poly(ethylene terephthalate) are, in comparison, most effectively protected against plasma attack. In the case of poly(styrene), where the rings are located as side chains, they are most efficiently degraded. (C) 1998 Elsevier Science Ltd. All rights reserved.
