Determination of polyolefin additives by reversed-phase liquid chromatography

This article examines the contribution of liquid chromatography to the study of polyolefin additives commonly used to obtain improved environmental resistance (antioxidants, ultraviolet light stabilizers, antistatics, and so on) and appearance enhancements ( e.g. colorants). Several reversed-phase liquid chromatographic methods are summarized, and a detailed description of different detectors is provided. In addition, ways of applying these methods to analyse food contact materials and plastic toys are emphasized. Finally, the potential use of these methods is addressed which complies with European health safety regulations.
