摘要
用混合晶红外光谱法和ＳＡＸＳ、ＤＳＣ和ＬＡＭ等方法研究了聚乙烯单晶在７５℃、９０℃和１０５℃退火前后的结构变化，发现在９０℃以下和１０５℃以上退火。
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℃.
