Abstract: Structure changes in polyethylene single crystals caused by annealing at 75, 90 and 105℃ were examined by the mixed crystal infrared spectroscopy, SAXS, DSC and Raman spectroscopy. It was found that different annealing mechanisms were obeyed below 90℃ and above 105℃.

Key words: polyethylene, deuterated polyethylene, infrared spectroscopy, single crystals, annealing
