Blends of poly(vinyl chloride) (PVC) with Poly(N-vinyl pyrrolidone) (PVP) were investigated by Fourier infrared spectroscopy (FTIR) and high-resolution solidstate 13 C cross-polarization/magic angle spinning (CP/MAS) nuclear magnetic resonance (NMR) spectroscopy. The intermolecular interactions betw

The solid-state Nuclear Magnetic Resonance (NMR) was used to characterize surfaces of silica gels chemically modified by alkenyltrialkoxysilanes and trialkoxysilyl terminated 1,4-polyisoprenes. The formation of covalent bonds created between alkoxy functional groups from alkenyltrialkoxysilane or tr
Silica gel, dealuminated zeolite USY and cesium-exchanged zeolite Y were impregnated with alkali metal hydroxides or acetates followed by calcination. Surface methoxy groups formed upon loading these samples with methyl iodide were applied as 13 C NMR spectroscopic probes to investigate the formatio
The chain conformation and hydrogen bonding in the crystalline and noncrystalline regions have been characterized for atactic poly(vinyl alcohol) (PVA) films prepared under different conditions by CP/MAS 13 C NMR analyses developed recently. The CH resonance lines of the crystalline and noncrystalli
