Solutions of polyacrylamide and poly(acry1amide-co-sodium acrylate) flocculants with varying molecular weights were shear degraded under a range of mixing conditions. The viscosity and flocculant activity of the solutions generally decreased with time to limiting values dependent on the mixing inten

The mechanical shear degradation of polydisperse polyisobutene and monodisperse polystyrene in oils of different viscosities in the concentration range of 0.1% to 1% was studied using a high-shear concentric cylinder viscometer under laminar and uniform well-defined shear field conditions. Molecular
## Abstract Viscosity measurements at a rate of shear between 10^4^ and 5 X 10^5^ sec^โ1^ were carried out with solutions of bovine fibrinogen (__c__ = 8.0โ18.4 mg/ml). The degree of anisotropy of the fibrinogen molecule estimated from the data is less than expected for Hall and Slayter's molecular
