Experiments have been devised which reveal serious shortcomings in the accepted method of interpreting the results of continuous and intermittent stress-relaxation measurements in terms of the Tobolsky two network theory. In general, the heat aging of rubbers is a complex process and there is a high probability that the results of stress-relaxation measurements will not be amenable to analysis by the two network theory.
