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 decrease
as 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.
