介绍了以各向异性有机载体为模板，通过茂金属催化聚合制备聚乙烯纤维的方法。通过静电纺丝得到聚乙烯醇和功能化聚苯乙烯纳米颗粒的混合物。在载体上加载MAO活化的茂金属并进行烯烃聚合后，得到的聚乙烯纤维具有芯鞘结构，直径控制在0.3-2 μm范围内。这种策略代表了一种直接的方法，可以在聚合过程中制造出定义良好的聚烯烃纤维和聚烯烃垫，而无需进一步加工。
The formation of polyethylene fibers via metallocene‐catalyzed polymerization using anisotropic organic supports as templates is presented. The supports are obtained by electrospinning a mixture of polyvinyl alcohol and functionalized polystyrene nanoparticles. After loading the MAO‐activated metallocene on the support and olefin polymerization, the obtained catalyst system yields polyethylene fibers displaying a core‐sheath structure with a controlled diameter in the range of 0.3–2 μm. This strategy represents a direct method to fabricate well‐defined polyolefin fibers and mats during the polymerization without any further processing.
