Description
Summary:The techniques of thermogravimetry and infrared spectroscopy have been combined in a unique method to provide quantitative and qualitative analyses of polymers. The amounts of additives, polymers, carbon black, and inorganic fillers are determined by thermogravimetry, and the additives and polymers are identified by infrared spectroscopy, all in one set of experiments. The method involves condensing the effluent from the thermogravimetric analyzer in replaceable glass tubes for transport to the infrared spectrometer. The method is illustrated with thermogravimetric and infrared analysis data for a Hypalon fuel hose and for a fluorosilicone fuel gasket. The main advantage of the method is the ability to collect as many separate fractions of the thermogravimetric effluent as required to identify the minor and major components of a polymer.
