The Filament Stretching Rheometry (FSR) method developed by Sridhar, McKinley and coworkers for polymer solutions has been extended to be used also for polymer melts. The design of a melt-FSR will be described and differences to conventional melt elongational rheometers will be pointed out. Results for LDPE up to 7 Hencky strain units show a maximum in the transient elongational viscosity followed by a steady stress. Also results for monodisperse PS fractions will be shown and discussed.
