摘　　要：叙述近年来超高拉伸,超高强度的超高分子量聚乙烯(UHMPE)的开发研究状况,特别对准稀溶液条件下凝胶形成法做了描述。阐述了UHMPE超高拉伸取向的结构特征,决定超高取向的微观机制及其极限结构和极限物性。并简要讨论了超高拉伸UHMPE的研究动向及应用前景。The development of ultradrawn ultra—high molecular polyethylene with ultra—high strength in recent years is reviewed in the article. Among these studies on methods, the dry gel deformation method from the semi—dilute solution is specially described. The structural models and micro—mechanism of ultradrawn orientation of UHMPE as well as its limit structure and physical property are also depicted. The research tendence and prospects on ultradrawn UHMPE in the future are simply discussed.
