Polymer AnalysisA method for the determination of down to 0.01% of water and organic volatiles in polyethylene and polypropylene.

Morsel

Copolymers and Condensation ProductsThis gas Chromatographic method is capable of determining styrene monomer and a wide range of aromatic volatiles in polystyrene and styrene-butadiene copolymers in amounts down to 50 ppm.

Additive MixturesThis thin-layer chromatography — spectroscopic procedure is capable of identifying and determining a wide range of additives in polymers in amounts down to a few hundred ppm. Several additives can be evaluated during the same analysis.

Indigence

Preliminary Qualitative IdentificationThis qualitative oxygen flask combustion method enables nitrogen, fluorine, chlorine, bromine, iodine, sulphur and phosphorus to be identified in polymers in amounts down to 0.01%.

Additive Mixturest least, to a particular class of additives such as phenolic antioxidants. Frequently, however, the analyst is faced with the problem of dealing with unknown additives in polymers, either single additives or, more commonly, mixtures of additives. He has first to identify the additive then determine

Preliminary Qualitative Identification of Polymersht arise as a result of an interest in the materials being used by competitors or manufacturers of components or packaging materials. Obviously, if a detailed examination of a polymer or copolymer and its additive system is required then other chapters of this book should be referred to. However, if
