Shear-Induced Orientational Order in a Polystyrene/Benzene-d6 Solution As Observed by 2H NMR

{{output}}
Using a home-built Couette-type shear cell we studied the behavior of a concentrated solution of polystyrene in benzene-d6 under shear. Deuterium NMR revealed a shear-dependent splitting of the benzene-d6 signal, indicating partial orientation of the polystyre... ...
