Abstract
The light scattered by benzene solutions of polystyrene up to a volume fraction of polymer of 0.62 has been measured. The results are compared with what was to be expected on the basis of recent thermodynamic theories for polymer solutions. This comparison has led to the recognition of a new and rapid method for estimating molecular weights. The method also seems to be a convenient one for obtaining thermodynamic information.
