摘要：
The orientational distribution function for the C-CD3 bond on the perdeuterated polymethacrylate chain of a liquid-crystalline side group polymer was determined in the frozen S-A phase by solid-state H-2 NMR. The results are compared with the ones of two similar systems recently reported. The slow chain dynamics above the glass transition was studied via 2D H-2 NMR, which indicates a diffusive motion constrained by the partial orientational order of the mesophase.
