Measurement of the bulk longitudinal modulus, M{sup *}, of rubbery polymers is a notoriously difficult task. Measurements are traditionally done through a fluid environment in methods that provide M{sup *} over only very narrow frequency ranges. An alternative approach, using a resonant test fixture is presented in this paper. A discussion of some physical limitations is developed. Among them are issues of repeatability and edge effects. A method of data analysis to address edge effects is also presented.
