Outline of Final Research Achievements

A novel optical rheometer was developed. Based on the fact that multiple types of chain conformations in the sample are sensitively reflected in the optical anisotorpies, not only the linear but also the circular anisotropies were examined. The aimed simultaneous measurement was performed successfully under the condition that both signals were comparable.
