摘要
冲击拉伸韧性和冲击拉伸力为衡量高聚物材料韧性不可缺少的指标。本文就低压线型聚乙烯的冲击拉伸韧性和冲击拉伸力与材料参数如密度、分子量的关系，以及不同性能原料共混物的配比对冲击拉伸性能的影响进行了系统的研究。
It is necessary for plastic material data-bank to absorb impulse-tensie data. This paper studied relationships between impulse-tensile toughness, impulse-tensile stress and material factors such as molecular weight and density for polyethylene, and each component's contribution to impulse -tensile properties of blends was also discussed. This work will give significent addition to basical data what polymer processing needs.
