| Outline of Final Research Achievements |
Segmental size for several polymer species is estimated from the dielectric and viscoelastic data for each polymer species. The result is quantitatively consistent with previous research. Details of the segmental mode are now under analysis.
In addition, the entanglement spacing is estimated for the miscible polymer blend from its viscoelastic data. The entanglement spacing in the blend deviates from the conventional expectation, possibly due to a specific interaction between the polymer species that leads to a surprisingly high miscibility.
