摘　　要：采用线性低密度聚乙烯(LLDPE)对双峰高密度聚乙烯(BHDPE)和高密度聚乙烯(HDPE)进行共混,测定共混物的力学性能和DSC曲线。结果显示共混物均可以产生共晶,LLDPE对BHDPE力学性能影响较大;在LLDPE/HDPE中添加BHDPE,三者共混物具有更好的力学性能,流变性能显示三者共混物体系黏度变化不大,为制备性能最优、成本最低的三者共混物提供了依据。BHDPE and HDPE were blended with LLDPE, the mechanical properties and DSC of the blends were investigated. The results showed that co-crystallization was formed and LLDPE had greater effect on the improvement of mechanical properties of BHDPE. By adding BHDPE to LLDPE/HDPE, a blend with better mechanical properties was prepared, while the viscosity changed litter.
