Microstructures of A 4(BC)4 star copolymers and the influence of architecture

The self-consistent field theory is used to investigate the microstructures of A 4(BC)4 star copolymers. The phase diagram is mapped out to show different phase regions. Compared with A(BC)4 star copolymers, several microstructures are lost, and more lamellar structures are found due to the stronger topological constraint of the junction. The results may be helpful to understand the influence of molecular architectures on microstructures and provide an effective way to design controllable microstructures.
