Abstract
The metallocene PE(m-PE)/HDPE and m-PE/LDPE blend systems show typical miscibleb behavior in the solid state. The yield strength and elongation decreased with the addition of m-PE, while the tensile strength at break, contrary to the yield strength, increased with the content of m-PE. The melting and crystallization behavior of the blend were dominated by HDPE. The melting temperature and the heat of fusion were linearly decreased with the m-PE content. This result shows that the metallocene PEs have a good low temperature heat-sealibility. The flow rate of blends under large load (21.6 kg) increased with the addition of m-PE, but the flow rate under small loa (2.16 kg and 5 kg) decreased with the m-PE content. The melt flow rate ratio decreased with the m-PE content while the torque value of blends increased. The results indicate that the processibility of m-PE/HDPE or LDPE decreases with m-PE content.
