摘要
超高分子量聚乙烯(UHMWPE)具有优异的使用性能,但是现有的商品化UHMWPE加工异常困难,严重限制了UHMWPE的大规模应用。低缠结UHMWPE相对于现有的商品化UHMWPE,分子链间的缠结更少,可加工性更好,为UHMWPE的生产、加工、应用开辟了一条全新的道路。文中综述了使用均相和非均相UHMWPE催化剂,制备低缠结UHMWPE的最新进展,并对低缠结UHMWPE在固态拉伸、烧结/挤压成型等方面的研究进展和应用前景进行了分析。
Ultra-high molecular weight polyethylene(UHMWPE)has excellent performance,but the existing commercial UHMWPE is extremely difficult to process,which severely limits the applications of UHMWPE.Compared with the existing commercial UHMWPE,the low-entanglement UHMWPE has less entanglement between the molecular chains and better processability,which opens up a new way for production,processing and application of UHMWPE.In this paper,the recent progress of homogeneous and heterogeneous catalysts for preparation of low-entanglement UHMWPE was reviewed,and the application prospects of low-entanglement UHMWPE in solid-state drawing,sintering/extrusion molding,etc.were analyzed.
