有机高分子与固体高分辨核磁共振

ORGANIC POLYMER MATERIALS AND SOLID-STATE HIGH-RESOLUTION NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY

主要介绍获得固体高分辨13C-NM R谱的CP/DD/M A S方法及其在复相结构的高分子微结构观测中的应用。

With the progress of computer technique, increasing magnetic field and various applications of new pulse programs, both liquid and solid state high resolution nuclear magnetic resonance are playing more and more important role in the determination of polymer chain structure. This article mainly introduces the CP/DD/MAS technique for solid-state high-resolution ^13C nuclear magnetic resonance （NMR） spectroscopy and its application on the determination of the phase structure of polyethylene powders, uni-axially oriented polyethylene films and PPO/PS blends.
