Paper Title:
Elongational Rheology of LLDPE by Melt Spinning Technique
  Abstract

Elongational rheology of LLDPE was studied by melt spinning technique. It was observed that the melt strength of LLDPE decreased with the rise of temperature, and the melts with lower elongational viscosities often broke at higher draw ratio. The melt strength activation energy was calculated by the slope of Arrhennius plots. The curves of elongational stress and viscosity under different conditions were drawn and compared, the results showed that with the increase of strain rate, the elongational stress rose and the viscosity decreased, both stress and viscosity dropped with the rise of temperature, and higher extrusion velocity caused lower elongational stress and viscosity.
