摘要: Abstract The high resolution 29Si NMR spectra of five solid silicon polymers different structure have been studied and the chemical shifts characteristic units determined. 29Si1H cross-polarization in combination with speed magic angle sample spinning power proton decoupling was used to achieve state spectra. Comparison latter results obtained liquid clearly indicates that no special effects on arise relations between δ(Si) molecular structure, well known from investigations liquids, can be for interpretation It is shown spectroscopy offers detailed information about structural siloxane resin framework, this opens up new possibilities determinations organosilicon polymers.
