Abstract
Polydispersity may be described by average diffusion coefficients. This work develops the theory for the determination of these coefficients with the Gouy interferometer. If a particular form of the distribution function of diffusion coefficients is assumed, number-average and weight-average molecular weights may be calculated. Two polystyrenes of broad molecular weight distribution are studied in cyclohexane at 35°.
