    Abstract:
    We derive an exact solution for a purely extensionalcylindrical filament of viscoelastic fluid that satisfies both the upper convected Maxwell and Oldroyd-B equations. The resulting prediction of decreasing filament thickness agrees with our experimental measurements for semi-dilute polymer solutions. In the limit of time to infinity, the exact solution approaches that for a Newtonian fluid.
