| 摘 要： | 将聚丙烯和石蜡油的混合物熔融挤出，使之在较高的应力场下冷却和相分离，得到了弹性聚丙烯中空纤维。这种部分结晶的弹性纤维可能具有平行排列的片晶结构，石蜡油存在于片晶之间。将石蜡油提取掉后稍加拉伸即可得到透气性很好的微孔中空纤维渗透膜。

| Abstract: | Elastic polypropylene hollow fibers were obtained from the blend of polypropylene and paraffin oil which was extruded in melt and then cooled in a high stress field (phase separation occurred). Such fibers may have row-nucleated lamella superstructure and the paraffin oil exists in the interlamellar region. Hollow fiber membranes with good gas permeability can be obtained after the extraction of the paraffin oil and stretching to a small extension. |
