Nanoheterogeneity in PEO/PMMA blends probed by129Xe-NMR
Autor: W. S. Veeman, S. Schantz
Publikováno v: Journal of Polymer Science Part B: Polymer Physics. 35:2681-2688
Xenon has been used as a structural probe of solid poly(ethylene oxide)/atactic poly(methyl methacrylate) (PEO/PMMA) blends of concentrations 10/90 to 75/25. 129Xe-NMR spectra at 293 K show significant changes in line width and chemical shift as the

Relation between molecular orientation and mechanical properties in differently processed polyamide 4.6/6 textile yarns
Autor: W. S. Veeman, R. Schreiber, R. Beyreuther, G. Schmack, H. Hofmann
Publikováno v: Journal of Applied Polymer Science. 66:377-385
A series of Polyamide 4.6/6 textile fibers spun according to different technologies, high-speed spinning, and the spin drawing, was investigated by 13C-NMR, ultrasonic, optical, WAXS, and DSC measurements. It was shown from the determination of the c

Aluminum-27 NMR studies of the calcium tungstate aluminate sodalite and sodium chromate aluminate sodalite, Sr8[Al12O24](CrO4)2 and Ca8[Al12O24](WO4)2
Autor: W. S. Veeman, J. J. van der Klink, Hans Schmid
Publikováno v: The Journal of Physical Chemistry. 95:1508-1511
The authors have studied {sup 27}Al NMR spectra of powders of strontium chromate aluminate sodalite (SACr) and calcium tungstate aluminate sodalite (CAW) by the magic angle spinning (MAS) technique and of single-crystal SACr by a static method. They

Application of 129Xe NMR to polymer blends
Autor: M. Mansfeld, W. S. Veeman, A. Flohr
129Xe NMR experiments on two different polymer blends are described. The first system, a blend of polypropylene (PP) and the copolymer of polypropylene and polyethylene (EP), shows separate domains of polypropylene and of the copolymer. The latter ph

Multiple-quantum nuclear magnetic resonance spectroscopy of coupled 1/2 spins in solids. Combination with cross-polarization and magic-angle spinning
Autor: Y, Ba, W S, Veeman
Publikováno v: Solid state nuclear magnetic resonance. 3(5)
Proton multiple-quantum coherence spectroscopy has been combined with magic-angle spinning (MAS) and cross-polarization (CP). This enables the detection of the proton (or any other abundant spin) multiple-quantum coherence spectrum via the high-resol
