摘要：
Differential thermal analysis (DTA) technique was used to determine the glass transition temperatures of polymethyl methacrylate (PMMA). When PMMA was adsorbed on α-alumina, DTA could not use to obtain the glass transition temperatures of the system PMMA/α-Al2O3. Inverse gas chromatography at infinite dilution proved to be an excellent technique to highlight glass transitions and local transitions of PMMA adsorbed on α-Al2O3, at various covered surface fractions.
