N2 - The study of phenomena transitions in polymers is of vital importance in material sciences and more particularly when polymers are adsorbed on oxides. Inverse gas chromatography (IGC) at infinite dilution proved to be an excellent technique to determine not only the glass transitions, but also β-transition and liquid–liquid transitions of polymers adsorbed on solid substrates. In this paper, we used the IGC technique to determine the second order transitions of the systems PMMA/SiO2 and PMMA/Al2O3, at various covered surface fractions and for various tacticities of the polymer (atactic, isotactic, and syndiotactic). In Part I, we developed the various theories, methods, and models used in the IGC technique in order to obtain physico-chemical properties when polymers are adsorbed on oxides.
