Abstract
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 SA phase by solid-state 2H 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 2H NMR, which indicates a diffusive motion constrained by the partial orientational order of the mesophase.
