Paper Abstract

Recent studies, mainly by DSC and NMR spectroscopy, have suggested the existence of a third phase in polymeric materials which is believed to be semi-ordered. The melting trace of polyethylene using a very slow temperature ramp (3K/h) reveals an order-disorder phase change in the melt. We want to confirm this important find by other techniques. This paper presents the use of FTIR to follow the melting process by analyzing the variation with temperature of the absorbance.
