The onset of tube-like constraining effects in polydisperse polymer melts

  • 35 Accesses

  • 1 Citations

Summary

This paper describes the onset of the influence of entanglement effects on the mobility of polymer chains in a polydisperse melt. Extending a scaling relation between the critical molecular mass of homodisperse melts and segment number density yields in the case of polydisperse melts a functional equation for the critical chain length. The case of the normal distribution will be solved and discussed.
