我们提出了一个明确定义的星形聚合物胶束模型系统的平衡链交换动力学的研究。结果表明，动力学遵循对数时间依赖性。同样的功能已被证实为其他两个胶束系统。这与理论预测和暗示形成鲜明对比，表明胶束核心内由几何约束引起的强耦合链动力学。
We present a study of equilibrium chain-exchange kinetics of a well-defined model system for starlike polymeric micelles. The results show that the kinetics follows a logarithmic time dependence. The same feature has been confirmed for two other micellar systems. This is in sharp contrast to theoretical predictions and hints towards strongly coupled chain dynamics within the micellar cores induced by geometrical constraints.
