| 摘 要： | 利用DSC、WAXD两种方法系统研究了LIDPE／EPO（线型低密度聚乙烯／乙烯丙烯辛烯－1共聚物）共混体系的相容性及结晶结构，通过DSC上（熔融峰，结晶峰）呈现单峰确定了此共混体系在水晶水平上共晶；用WAXD方法，计算了共混体系的结晶度，晶胞参数及微晶大小随组成不同而变化的关系，进一步证实了LLDPE／EPO共混体系的相容性。

| Abstract: | The crystallization structure and compatibility of LLDPE/EPO (linear low density polyethylene/ethylene-propylene-octene-1 copolymer) blends have been studied by differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) methods. Only a single melting or cooling peak was found in DSC curves for all blends, showing cocrystalline in patch-crystal level. The crystallinity?unit cell parameters and crystallite-size of the blends which have been calculated by WAXD method are in dependence of the composition of the blends, further revealing compatibility of the system. |
