Aging Studies of Filled and Unfilled VCE

摘要

This report presents data on the effects of temperature and gamma radiation on the chemical and structural properties of both filled and unfilled VCE material produced by the Kansas City Plant using WR-qualified processes. Thermal effects up to 300 C and gamma irradiation doses of 1 MRad and 25 MRad were investigated under atmospheric conditions. Characterization techniques used in the study comprise Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Tensile Testing, Solid Phase MicroExtraction - Gas Chromatography/Mass Spectrometry (SPME-GC/MS), phenol extraction followed by HPLC, and various Nuclear Magnetic Resonance (NMR) techniques including: (sup 13)C, (sup 13)C (l-brace)(sup 1)H(r-brace) cross polarization (CP), (sup 1)H magic angle spinning (MAS), 13C(l-brace)(sup 1)H(r-brace) Wide-line-Separation (2D-WISE) and development of Center band-Only Detection of Exchange (CODEX).
