Abstract
The method of Menefee and Peticolas for obtaining the molecular weight distribution of linear polymers from stress relaxation after steady-state flow has been applied to data on melt samples: a linear polyethylene and polystyrene sample. The results offer considerable promise for a rapid estimation of the high molecular portion of the distribution curve. The method is based on a rather straightforward extension of the theory of Roase to bulk molten polymers. A discussion of the validity of this process is given in the light of recent developments.
