H. Elastic breakup in simple shear of melts
The ultimate question is to determine whether our observations from entangled PBD solutions would apply to entangled melts. Can we apply what we learned from rheology of entangled solutions to describe and anticipate nonlinear flow behavior of entangled melts? We have succeeded in our pursuit along this direction.
