Molecular weights from GPC curves are determined for EPM, EPDM, and some polybutadienes. The determinations make use of a Benoit factor, B, which is defined and tabulated for the polymers studied. The use of this factor provides a convenient method of employing the Benoit hypothesis. The M n from the GPC curves are compared with osmotic molecular weights to provide additional confirmation of the Benoit hypothesis. The M v from the GPC curves are used with intrinsic viscosity data to establish [η]–versus– M relations.
