Notes:
The post extrusion swelling behavior of PVC has been studied as a function of the rheological flow variables and as a function of the molecular weight of the polymer. An expression which correlates the swelling with the apparent non-Newtonian viscosity has been found for each of the five molecular weight samples studied. No mechanism for this elastic effect was proposed.
