LDPE also has a broader molecular weight distribution(MWD).Again,a polymer with a broader MWD also exhibits a higher shear-thinning behaviour.On the contrary,mLLDPE echibits a narrower MWD,and therefore,the viscosity does not decreaseas much at higher shear rates.Comparing figures 2.and3,it is quite evident that the zero-shear viscosity of LDPE is much lower than that of mLLDPE and LLDPE.
