Abstract
Sedimentation velocity measurements have been performed in polystyrene-cyclohexane solutions at 35.4 °C. The use of extremely high molecular weight fractions, up to 20.6 x 106, has enabled us to study the concentration dependence of the dynamic correlation length in the semi-dilute regime. ξH scales as c-0.96 ± 0.04 in agreement with theoretical predictionsKeywords
