Light Scattering by Solutions of Flexible Macromolecules Subjected to Flow

Abstract
A coaxial‐cylinder flow assembly is described in which the changes of the intensity of light scattered by solutions of a flexible polymer (polystyrene in cyclohexanone) with flow have been determined over a range of angles and up to velocity gradients of 10 000 sec−1. The results show that flowscattering is concentration dependent and that at low concentrations the theory of Peterlin and Reinhold is approximate description.
