将高密度聚乙烯(PE-HD)、低密度聚乙烯(PE-LD)、聚乙烯-辛烯共聚弹性体(POE)经双螺杆挤出机制成不同比例的PE-HD/PE-LD材料。采用差示扫描量热(DSC)仪和X射线衍射(XRD)仪分析了不同厚度下PE-HD及其PE-HD/PE-LD复合材料的聚集态结构。DSC实验表明复合材料相容性良好且形成了共晶，XRD结果则显示材料的拉伸强度与其结晶度和晶粒尺寸都有关。

High density polyethylene(PE-HD),low density polyethylene(PE-LD) and polyethylene-octene copolymer elastomer(POE) were extruded into different proportion PE-HD/PE-LD material by twin-screw extruder. The aggregation structure of PE-HD and its composites under different thickness were studied by differential scanning calorimetry (DSC) and X-ray diffraction instrument(XRD). DSC experiment show good compatibility of composites and form eutectic. XRD results display that tensile strength are both related to its crystallinity and grain size.
