| Research Abstract |
On the basis of poly(N-isopropylacrylamide) chains, new telechelic polymers carrying various functional groups at the chain ends were synthesized. Their dilute solution properties were measured. Their self-assembled structures, such as flower micelles, mesoglobules, networks, etc were studied by neutron scattering and theoretical analysis. Nonlinear rheological properties, such as thickening, strain hardening, stress overshoot, banding etc were studied on the basis of transient network theory. Their molecular origin was clarified.
