摘要
Time-resolved small-angle X-ray scattering is used to investigate the time dependence of structure formation at the ordering transition in bulk diblock copolymers. After a quench from the disordered into the ordered state two relaxation processes are found on well-separated time scales. The slow process displays an unusual temperature dependence and is discussed as a nucleation phenomenon.
