2006 (English)In: ACS Symposium Series: Degradable Polymers and Materials, Principles and Practice / [ed] Kishan Khemani and Carmen Scholz, American Chemical Society (ACS), 2006, 1, 307-319 p.Chapter in book (Refereed)
Indicator product concept, chromatographic fingerprinting in combination with multivariate data analysis and total luminescence intensity (TLI) are presented as tools for product evaluation, quality control and testing of degradable polymers. A correlation was shown between the number of chain scission and the release of dicarboxylic acids during photo-and thermo-oxidation of polyethylene. This opens for degradation state prediction from the amount of indicator products released. Multivariate data analysis of chromatographic fingerprints of dicarboxylic acids allowed classification of polyethylene materials both with respect to the degradation state and pro-oxidant system. Total luminescence intensity proved to be an excellent tool for early degradation detection and classification of polyethylene materials. Further applications could include classification of materials with respect to durability or degradability, evaluation of antioxidant or pro-oxidant
