Solid-state NMR offers a unique way to monitor the local and collective chain motions in semi-crystalline polymers. In this review paper, we will briefly survey recent results on the solid-state NMR study of chain motions in semi-crystalline polyethylenes (PEs). We will demonstrate that the state-of-the-art solid-state NMR now can provide very detailed knowledge about the local and collective chain motions in semi-crystalline PEs, which is of great relevance to our understanding of the mechanical behaviors of polyethylene in the microscopic level.
