Abstract

The method determining relative average molecular mass and distribution of HDPE by Gel Permeation Chro- matography was established.Relative average molecular mass and distribution of HDPE was determined.The results showed that samples possessing GPC double peaks have broader molecular mass distribution and the method has good reproducibility.The results were not obviously affected by the solution concentration from 1.0mg/mL to 2.5mg/mL.
