Double-grafted ABC comblike copolymers with 1, 2, 3, 5 and 10 periodic star structures in their sequences are investigated by using the Self-Consistent mean Field Theory. These comblike copolymers can be considered as a sequential linkage of several four-arm star copolymers through their C arms. The effect of such linkage on their phase behaviors is investigated by comparing their triangular phase diagrams, critical order-disorder transition values and the domain spacing of the equilibrated microphases. The values increases with the number of periodic star structures in copolymer sequence and also increases with the volume fraction of C arms in the melt-state comblike copolymers as =10.5 . The domain spacing of the lamellar phase increases with both and the length of C arms as ~ . With increasing , the influence of on the triangular phase diagrams weakens for the comblike copolymers. |
