Abstract: In determination of polymer transitions by inverse gas chromatography (IGC),traditionally,specimen of sample coated beads and intermittent heating technique have been employed Instead,in this work, the experimental procedure was simplified by using powder specimen and continuous heating to investigate the possibility of establishing a fast method for determining polymer transitions.Our results show that the proposed method is feasible and that the use of peak height vs temperature plot for characterizing the transitions and other structural changes of a polymer will further simplify the treatment of experimental data.
