Abstract : In previous work, a static multi-modulus technique was used for the simultaneous determination of Young's and bulk moduli on a single specimen of several polymeric materials. Now additional data have been obtained on a series of plasticized polyvinyl chloride polymers, on a series of polyphenyl-quinoxalines, cured with varying amounts of crosslinking agent, and on several other individual polymers. All the new data fit the same pattern as the earlier data. It was found that there is an optimum plasticizer content for PVC which maximizes moduli characteristics. In the case of the polyphenylquinoxaline, the elastic properties remained constant at all crosslinking agent concentrations. (Author)
