    Phase Structure Changes in Polyethylene and Ethylene Copolymer at Room Temperature as Studied by Solid-state High-resolution 13 C NMR

      摘要
    • 摘要: 采用固体高分辨＾１３ＣＣＰ／ＭＡＳ方法跟踪测量了熔融淬火的聚乙烯样品及冷冻抽干的乙烯共聚物样品的相态结构在室温下随时间的变化，通过计算机拟合，观察到两种样品中的单斜晶、斜方晶并对该现象产生的机制给予了解释。

       

      Abstract: The changes of the phase structures in melt-quenched polyethylene and freezing-dried ethylene copolymer samples maintained at room temperature are investigated by solid-state high-resolution 13 C NMR spectroscopy. By computer-fitting of the NMR spe
