Abstract
The molecular theory proposed by Doi and Edwards is applied to the determination of the rheological behaviour of a technical polystyrene with medium molecular weight and rather broad molecular weight distribution. The molecular parameters of the polystyrene were measured by means of the GPC method. The rheological properties of the sample were investigated by means of a dynamic viscometer. It is shown that a good description of the linear viscoelastic properties of the melt of the polystyrene can be given using the Doi-Edwards theory combined with a mixing rule of simple superposition of the moduli according to the number fractions of the molecular weights.
