✦ Synopsis

A method is developed for testing extrapolation procedures of shear stress-shear rate data by using the dependence of the flow activation energy on shear. Three polyethylene types are studied, and it is concluded that the difference in flow activation energy observed between conventional low density polyethylene and high density polyethylene is due mainly to long chain branching.

A new rheological method for the determination of the molecular weight distribution of polymers was developed using the critical viscosity for entanglement together with the Newtonian viscosity and the apparent viscosity at a shear stress in thenon-Newtonian region.
