采用哈克转矩流变仪对苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物（SEBS）与高密度聚乙烯（HDPE）进行共混，研究了不同HDPE含量和品种对SEBS/HDPE共混体系加工性能、力学性能和拉伸性能的影响。结果表明，当HDPE含量达到20份时，共混物的冲击性能和拉伸性能明显提高，流动性也得到改善，表明SEBS/HDPE共混比为100/20时是一种理想的共混体系。
Styrene-ethylene/butylene-styrene block copolymer(SEBS) and HDPE were blended by using Haak torque rheometer,and the effects of different contents and variety of HDPE on the processability, mechanical properties and tensile property of styrene-ethylene/butylene-styrene block copolymer/high density polyethylene (SEBS/HDPE) were studied. The results showed when the content of HDPE was up to 20 phr, the impact and tensile properties of the blend increased obviously, and the flowability of the blend was also improved, which showed that SEBS/HDPE with a blending ratio of 100/20 was an ideal blend system.
