Abstract
Apparent elongational viscosity studies were made on dilute solutions of high molecular weight polymers using a fiber spinning apparatus des igned for Low shear viscosity liquids with substantial elongation effe cts. The experimental method involved the flow of solutions of polyacr ylamide and poly(ethylene oxide) from a tube into an evacuated vessel. Experimental results showed that the apparent elongational viscosity obtained from the jet shape increased linearly with the stretch rate.
