摘　　要：研究了茂金属线型低密度聚乙烯(mLLDPE)、mLLDPE/低密度聚乙烯(LDPE)共混物的热性能、流变性能及薄膜样品的基本性能。热性能结果表明,在mLLDPE中添加LDPE使样品的结晶温度明显下降;毛细管流变试验结果表明,LDPE的添加使mLLDPE的剪切敏感性显著提高,利于其加工;薄膜样品性能研究结果表明,mLLDPE使得LDPE的力学性能明显提高,光学性能明显改善。The basic capability of mLLDPE, mLLDPE/LDPE blends was analyzed, including thermal properties, rheological property, and the basic performance of the film samples. From the thermal properties analysis it showed that the crystallization temperature of the sample declined obviously when LDPE was added to mLLDPE. From the capillary rheological test it showed that the shear sensitivity was increased, and the process ability of mLLDPE was better. From the study of the film sample it showed that the optical property and the mechanical property of the LDPE were improved obviously.
