Asymmetrically composed diblock copolymers exhibit multiphase behaviour and transit the lamellae, gyroid and hexagonal cylindrical phases before reaching the order–disorder temperature, TODT. During a heating experiment towards TODT we observe that birefringence measurements are more sensitive than dynamic mechanical testing and have faster data acquisition rates than SANS when used to follow transient states of the sample. However, birefringence measurements cannot alone identify the precise phase behaviour.
