Polyethylene using high-field carbon

Characterization of Long-Chain Branching in Polyethylenes Using High-Field Carbon-13 NMR... [Pg.93]

Besides determination of stereosequences, high-field carbon-13 NMR can be used to trace out chain branches and end groups by precise signal area measurements with an accuracy of 0.01 to 0.02%, as verified for polyethylene samples [528]. [Pg.311]

To illustrate the use of PIXE and micro-PIXE in the study of breakdown phenomena in polyethylene high voltage cable insulation and other related topics we will describe a few typical measurements, first the study by standard PIXE of impurities in the organic semiconductor H2PC and in the carbon black semicon used in high voltage cables. Examples of the use of the microbeam to study some electrical and water trees as well as the diffusion of impurities from the semicon into polyethylene under typical electric field and humidity conditions will be given. [Pg.118]
