Chemical Characterization of Polyethylene Resins and Polyethylene Gas Pipe

摘要

Three analytical techniques were used in this study to characterize chemically commercial polyethylene pipe samples: carbon-13 nuclear magnetic resonance ( exp 13 C NMR) for looking at branching in the polyethylene, gas chromatography/mass spectrometry (GC/MS) for characterizing some of the low molecular weight components of polyethylene gas pipe, and x-ray diffraction (XRD) for determining the degree of crystallite orientation and crystallite size of the polyethylene within the polyethylene pipe matrix. Results are discussed. 9 figs., 6 tabs. (ERA citation 10:048170)
