Abstract

The synthesis, structure and dynamics of model ABC diblock copolymer are investigated. The blocks are: A, polystyrene; B, zwitterion; and C, polyisoprene. The structure is studied with small angle X-ray scattering and rheology. It is found that inserting the short B block within the A-C junction decreases the miscibility of the AC diblock. Moreover at the order-to-disorder transition temperature both the microstructure and the aggregates dissolve. The location of the functional group at the PS-PI junction makes the system suitable for probing dynamics of the polar group within the interface. For this purpose, a dielectric spectroscopic is used to study the local, chain and slow dynamics in the ordered state.
