Use of Reversed Gas Chromatography in the Investigation of Polymeric Compounds

The principal aspects of the use of gas chromatography for investigating polymers when they are employed as a stationary phase (the reversed gas chromatographic method) are considered: the identification of polymers, the determination of their molecular weights, the study of the thermodynamics of the dissolution of low-molecular-weight substances in polymers, the determination of the temperatures of the phase transformations, degrees of crystallinity, kinetics of crystallisation processes, and the chemical changes taking place in the polymers.
The theoretical principles of the use of reversed gas chromatography and the peculiarities of the gas-chromatographic behaviour of polymers determined by the structure and their phase and physical states are discussed.
