Abstract
The apparatus and the principle to measure flow small-angle light scattering (“flow-SALS”) are presented as one of the rheo-optical techniques. The flow-SALS technique presented here enables one to investigate small-angle light scattering profiles and rheological properties of polymer solutions, liquids, and mixtures, as well as polymer liquid crystals under various types of shearing, i.e., steady-state shear flow, oscillatory shear flow, and shear recovery after the cessation of steady-state flow. This technique may be useful to investigate the flow-induced formation, dissolution, and deformation of supermolecular structure with spatial correlation length of a few microns, and also their effect on rheological properties. In order to demonstrate the prospect of its use, some preliminary results on flow-SALS from the lyotropic polymer liquid crystal [20 wt% poly(γ-methyl-d-glutamate) in m-cresol] are presented.

According to the result reported by Itoh,26 the 20 wt% solution should have θmax=2.1° (in the medium) and 3.3° (in the air), and hence the scattering maximum should exist in the angular range covered in this experiment.
