摘　　要：本文利用ＲＨＥＯＧＲＡＰＨ２００２型高压毛细管流变仪对国产高密度聚乙烯（７０００Ｆ、６０９８、２４８０、５２００Ｂ、５０００Ｓ、２２００Ｊ、７００６Ａ）的不稳定流动及影响因素进行了研究，为国产高密度聚乙烯的成型加工提供理论依据和基础数据．In this paper,the melt fracture and melt slip of high density polyethylene(HDPE) made in china as well as their influence factors were studied by a high pressure capillary rheometer,RHEOGRAPH 2002,at a large range of shear rate and temperature.The results can offer theoretical basis for HDPE processing.
