The 10% solution viscosity has been used extensively as a measure of molecular weight for the commercial production of polystyrene. Recently, poor correlations have been observed between 10% solution viscosity and molecular weight as measured by gel permeation chromatography. Lowering the concentration improves the correlation. At 0.2%, the log–log plot of viscosity versus molecular weight becomes linear.
