Flow-induced alignment of two lamellar forming diblock copolymers, one with components having different viscosities and another having almost the same viscosities are compared based on the interaction parameters, (χN) eff, of the components. It is concluded that the degree of perpendicular alignment (ratio of sector averaged intensities) is primarily determined by (χN)eff and reduced shear rates. In addition, concentration and shear rate regions in which parallel alignment coexists become narrower for the diblock copolymers consist of components with almost the same viscosities.
