NSE Results from Polymer Blends and Block Copolymers

2 NSE Results from Polymer Blends and Block Copolymers 

NSE measurements at zero average contrast conditions on a symmetric diblock copolymer of H-PS and D-PS dissolved in an appropriate mixture of proto-nated and deuterated benzene are reported [171,172]. The measurements were performed at different concentrations c c. For comparison, the interdiffusion of a corresponding blend of H-PS and D-PS homopolymers dissolved in deuterated benzene was studied, too [171]. Owing to the relatively low molecular masses, only the regime Q R2 1/2 1 was accessible, and the internal modes could not be probed.
