摘要：

A transition from a body-centred cubic structure at room temperature to a face-centred cubic structure at higher temperature has been observed in a solution of a poly(oxyethylene)-poly(oxybutylene) diblock copolymer. The ordered micellar structures were confirmed using small-angle X-ray scattering by preparing oriented domains via steady shearing in a Couette cell. The effect of shear in generating highly oriented, twinned cubic domains is discussed.
