Fourier Transform Infrared Spectroscopy : Low Density Polyethylene, High Density Polyethylene, Polypropylene and Polystyrene Eman Mousa Alhajji North Carolina State University Department of Materials Science and Engineering MSE 255 Lab Report 203. A. Patrick Snyder 3/13/2016. Abstract The objectives of this experiment are to analyze the vibrational properties and Fourier Transform Infrared Spectroscopy (FTIR) measurements of four polymers assigned to unknown spectra, examine how different bonds and functional groups give rise to different FTIR signatures and estimate % crystallinity in LDPE and HDPE as semi-crystalline polymers.
Mar 13, 2016 · spectrum of a 100% crystalline PE sample, Ia is the intensity of crystallinity methylene rocking peak and Ib is the intensity of amorphous methylene rocking peak. Results The FTIR spectra were calculated and given without the samples’ names. Sample A indicates 10 major peaks, as labeled in Figure 3.
