Summary

In this chapter the important viscoelastic properties of ordered block copolymers are discussed. The localization of the apparent order-to-disorder transition temperature through rheology is discussed together with the viscoelastic spectrum of block copolymers that includes segmental modes, chain relaxation and structural relaxation. The viscoelastic response of the different ordered phases is provided. The use of flow as an efficient and versatile means of obtaining macroscopic alignment is explained and experimental results from small-angle X-ray scattering and optical birefringence as well as computer simulations depicting the different alignment trajectories are provided.
