Initial Aging Studies of Unfilled VCE

[摘要] This report presents initial data on the effects of temperature, oxygen, and radiation on the chemical and structural properties of newly formulated, unfilled VCE. This initial effort focused on a pristine sample, and a replicate sample irradiated in air at a dose of 25MR. Thermal degradation was investigated by performing Thermogravimetric Analysis (TGA), and radiation-induced degradation was investigated using Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Solid Phase MicroExtraction--Gas Chromatography/Mass Spectrometry (SPME-GC/MS), as well as various Nuclear Magnetic Resonance (NMR) techniques including: {sup 13}C, {sup 13}C {sup 1}H cross polarization (CP), and {sup 1}H magic angle spinning (MAS) NMR.
