The stability of the spherical copolymer micelles with respect to formation of the ordered morphologies is theoretically studied in the spirit of the weak segregation theory pioneered by Leibler and generalized by the author to cylindrical ordering (bottlebrushes). The symmetry of the morphology emerging is described by the dominant spherical harmonics of the composition profile. It is shown that, due to deep mathematical reasons, the symmetry of the ordered morphologies is strongly dependent on the micelle radius R, a series of the ordering transitions being expected with changing R. The general statements of the theory are illustrated via microscopic calculations for symmetric diblock copolymers.

从Leibler率先提出并由作者推广到圆柱有序化（瓶刷）的弱偏析理论的精神，理论上研究了球形共聚物胶束相对于有序形态形成的稳定性。组成轮廓的主要球形谐波描述了出现的形态对称性。结果表明，由于深层的数学原因，有序形态的对称性很大程度上取决于胶束半径R，随着R的变化，一系列的有序过渡是可以预期的。该理论的一般陈述通过对称二嵌段共聚物的微观计算来说明。
