Hereunder is given the report of investigation made of melt rheology of high density polyethylene.
Its linear viscoelasticity, capillary flow properties and molecular weight parameter were measured with plate relaxometer, Koka Flow Tester and gel permeation chromatography, respectively.
It is found that there are intimate correlations among the slope of relaxation modules curve, non-Newtonian flow behavior, the Barus effect and molecular weight parameter, MZ·MZ+1/MW, respectively.
