Dynamic structure factor for random block copolymer investigated by neutron spin echo technique

Endo, Hitoshi; Takano, Atsushi*

The dynamic structure factor of random copolymer was investigated by neutron spin echo technique. The theoretical dynamic structure for random copolymer was derived theoretically, which was deviated from that of homo polymer. Our experimental results supported this theoretical prediction. Furthermore, it became apparent that the theory based on Gaussian approximation violated gradually from large to small space.
