Structure Formation and Molecular Motion of Temperature-Responsive Telechelic Associating Polymers

在聚N-异丙基丙烯酰胺链的基础上，合成了链端带有各种官能团的新型遥控聚合物。测定了它们的稀溶液性质。用中子散射和理论分析研究了它们的自组装结构，如花状胶束、介球、网状结构等。基于暂态网络理论，研究了材料的增稠、应变硬化、应力超调、条带等非线性流变特性。阐明了它们的分子来源。

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.
