| Outline of Final Research Achievements |
In this work, we focus on investigations of slip at the interface between two immiscible polymer melts by rheological method, confocal microscopy and high-speed birefringence microscopy. We modified Mooney method, usually used to investigate wall slip, to investigate polymer/polymer interfacial slip. To determine the validity of the modified Mooney method, we also determined the slip velocity by using the slip-induced deviation from non-slip condition variables. We use PP and PS with almost identical shear rate-dependent viscosities over a range of shear rates. The slip velocity obtained from the modified Mooney method displayed excellent agreement with that determined using the deviation from no-slip.We found discontinuous velocity distribution of PS/PP interfaces by in-situ observation inside the glass window. This is consistent with the capillary flow experiments.
