Abstract
The normal coordinate theory of viscoelasticity has been shown to provide a bridge between the measurable rheological properties of linear polymers and their molecular weight distribution functions, as well as their average molecular weights. Equations have been derived relating the molecular weight distribution function of a linear polymer to a sum of functions of a measurable rheological property such as stress relaxation or dynamic viscosity. Thus, a method for the simple and rapid determination of molecular weight distribution has been developed within the limitations of the normal coordinate theory.
