Awesome video once again! Is there an easy explanation how Trouton viscosity for LDPE is lower? I would assume it's higher due to potential entanglements from the branches.
@andrewmountianou2697 thank you very much! Yes, it's all about branching an the subsequent entanglements that result! More entanglement results so higher strain hardening!

@@drbartsworldofchemeng Thanks but why Trouton predicts a lower viscosity for low density?
I got it, these where shear viscosities multiplied by a constant the T ration, not a real prediction.
