Understanding and Control of High Temperature Oxidation Flaws of Low-Density Poly(ethylene) with Raman Spectroscopy

Figure 7

Evolution of the scores in function of the first and the second loading. Disk spectra corresponding to four scores are represented as a function of the oxidation degree: (a) nonoxidized, (b) weak, (c) medium, and (d) strong oxidation. The diminution in intensity of the Lorentzian peaks and the increase of the amorphous peaks show the impact of oxidation on the polymer crystallinity.
