摘　　要：挤出胀大和熔体破裂不仅是高分子流变学研究的热点,而且对工业生产有重要的指导作用。文中回顾了近五年来在挤出胀大和熔体破裂方面的研究进展,并简要介绍了国内外降低或消除挤出胀大和熔体破裂的主要方法。Understanding the extrusion swell and melt fracture which occurs when a polymer melt is extruded through a die is a longstanding problem in the plastics and chemical engineering communities. These issues are of large technological importance for the plastics industry. In this paper, we reviewed the investigation of extrusion swell and melt fracture about the five past years, and introduced some methods on how to reduce or eliminate them.

关 键 词：挤出胀大 熔体破裂 降低
