| 摘 要： | 将聚丙烯树脂在熔融指数仪上熔融挤出、快速牵伸并退火处理,制得了硬弹性聚丙烯纤维。不同纺丝条件下得到的纤维试样的WAXD、SAXS、DSC、密度、双折射及动态力学性能的测试结果表明,硬弹性聚丙烯纤维除了具有平行排列的片晶超结构外,另一重要的结构特点是非晶区分子链具有较好的活动性。

| Abstract: | Hard elastic polypropylene fibre samples were made by melt spinning isotactic polypropylene with melt indexer, followed by fast winding and annealing. The results of WAXD, SAXS, DSC, density, birefringence and dynamic mechanical study under different conditions showed that, besides the lamellar structure which is perpendicular to fibre direction, the less restrained molecular layers between lamellea are the main feature of hard elastic polypropylene fibre structure. |
