    "abstract": "We studied the microscopic polymer conformations in the droplet detachment\nprocess of an elastic semi-dilute polyelectrolytic Xanthan solution by\nmeasuring the instantaneous birefringence. As in earlier studies, we observe\nthe suppression of the finite time singularity of the pinch-off process and the\noccurrence of an elastic filament. Our microscopic measurements reveal that the\nrelatively stiff Xanthan molecules are already significantly pre-stretched to\nabout 90 % of their final extension at the moment the filament appears. At\nlater stages of the detachment process, we find evidence of a concentration\nenhancement due to the elongational flow.",
