Experimental Analysis of the Extensional Flow of Very Weakly Viscoelastic Polymer Solutions

We study with ultra-high-speed imaging the thinning of the filament formed during the breakup of a pendant droplet of very weakly viscoelastic polymer solutions of polyvinylpyrrolidone (PVP) and polyethylene oxide (PEO). In the latter case, we consider two molecular weights: <inline-formula> &...
