| 摘 要： | 研究了超高相对分子质量聚丙烯（UHMWPP）的加入对超高相对分子质量聚乙烯（umfwPE）冻胶体系粘性行为、非牛顿指数、结构粘度指数的影响。结果表明：UHMWPP在UHMWPE／UHMWPP共混体系中起到了润滑剂的作用，使体系的表观粘度降低，非牛顿指数升高，结构粘度指数下降。其中，UHMWPP添加量为5％时，冻胶体系的可纺性最佳。 |

| Abstract: | The influence of UHMWPP(ultra-high molecular weight polypropylene) on the rheological behavior of UHMWPE(ultra-high molecular weight polyethylene) gel system was studied,as were the non-Newtonian index and the structural viscosity index.The results showed that UHMWPP plays a role of lubricant,which could decrease the apparent viscosity and structural viscosity index and increase the non-Newtonian index.And UHMWPE/5%UHMWPP gel system exhibits the best spinnability. |
| Keywords: | ultra-high molecular weight polypropylene ultra-high molecular weight polyethylene gel rheological behavior |
