The orientation dynamics of a monolayer of a nematic polymer solution were examined for both extensional and simple shear flows. In extensional flow, a 'strong flow/weak flow' criteria was investigated and found to occur at a critical rate of strain that was predicted by the simple molecular model of Doi and Hess. In simple shear flow, evidence of director wagging and flow alignment was obtained.

Abstract
The orientation dynamics of a monolayer of a nematic polymer solution were examined for both extensional and simple shear flows. In extensional flow, a 'strong flow/weak flow' criteria was investigated and found to occur at a critical rate of strain that was predicted by the simple molecular model of Doi and Hess. In simple shear flow, evidence of director wagging and flow alignment was obtained.
