Both the scattering and rheological results indicated that the phenomenon similar to"double cloud point", which has been found along the vorticity direction by previous studies, could be also observed in the velocity direction, which confirms the prediction of the above theory that the polymer blend will exhibit anisotropical complex phase diagram under shear. It's also found that the mixing along vorticity direction was reduced by weak shear but enhanced by strong shear. In addition, the more remarkable the molecular weight differences between components, the more prominent the shift of the apparent phase boundary along vorticity direction.

除了以往研究发现涡流方向存在&双浊点&现象以外在，本文的光散射和流变测试均显示，剪切场下体系在流动方向上也出现了类似&双浊点&的现象，证实了上述理论模型关于剪切场会导致二元高聚物共混体系出现各向异性的复杂表观相图（例如Miscibility Gap现象）的预测；同时发现弱剪切会导致体系涡流方向上的相容性减小，而强剪切则在该方向上增强相容性；另外，两组分分子量的差异越大，表观相界的移动越显著。
