摘要
介绍了1种测定表观拉伸流动性能的新方法,通过测量不同聚合物的拉伸流动阻力和表观拉伸应变速率,来比较它们的加工流动性能,并就低密度聚乙烯和线型低密度聚乙烯的分子结构对加工流动行为的影响进行了探讨。
A new method for determining apparent elongational flow characteristic was presented in this paper. The processability of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) resins under same specified conditions was compared through the measurements of their resistance to elongational flow and apparent elongational strain rates. The effects of molecular structure of LDPE and LLDPE on their flow behaviours during the processing were also outlined.
