Anomalous diffusion of chains in semicrystalline ethylene polymers.
The chain diffusion between crystalline and amorphous/interfacial regions in semicrystalline ethylene homo- and copolymers was investigated by means of solid-state NMR. It was found that the crystalline chain segment diffusion along the chain-folded path is anomalous and can be characterized by the scaling relation of mean-square displacement, <s(2)> approximately t(1/2).
