摘　　要：针对超高分子量聚乙(烯UHMWPE的)分子量大、熔体黏度高、临界剪切速率低和摩擦系数小而导致不易成型加工的问题重,点阐述了近几年UHMWPE的国内外成型加工技术最新进展包,括高速模压成型、固态挤出成型、气辅挤出成型及激光烧结成型等,并指出了提高黏均分子量1 000万以上的UHMWPE的加工效率是当今该领域的重要研究课题和发展方向。The latest processing techniques of ultra high molecular weight polythene（UHMWPE） were summarized according to the problem that it was difficult to process UHMWPE due to its high molecular weight,high melt viscosity,low critical shear rate and friction coefficient,such as high velocity compaction,solid-state extrusion,gas-assisted extrusion,laser sintering processing,and so on.Research trend of UHMWPE was predicted.It points out that how to improve the processing efficiency of UHMWPE with molecular weight exceeding 10 000 000 is an important research subject.
