ABSTRACT:
A method of accurately determining the degree of resin coating on the conductive particles in a conductive molding composition for a conductive, high density information disc at various stages in the manufacturing process as well as in the finished disc through the use of electron spin resonance techniques. The method is likewise useful in evaluating proposed changes in the formulation and processing parameters of the conductive molding composition.
