The non-Newtonian behavior of commercial linear polyethylene samples and their fractions were studied a t 190OC. The viscosity q versus shear rate 9 curves of whole polymers could be superimposed onto a single master curve despite the variations of their molecular weights and molecular weight distri
The thermodynamic relations between the melting point (MP) and the size of crystals are derived by the use of the Kelvin equation. The results show that the MP depression increases with a decrease in size of a crystal and that there exists the lowest MP when the partial derivative of the surface ten
