The relative abilities of eight molecular models to describe the response of a cross-linked polymer network to general biaxial deformations are tested. The reduced two-parameter models of Flory and Erman and Ball, Doi, Edwards, and Warner and, to a more limited extent, the reduced one-parameter Gaylord model are found to be able to account for large portions of the published experimental data. However, none of the eight models can reproduce the negative W2values that are observed at very small strains. It is shown that the reduced curve method of Treloar for the representation of biaxial data is inferior to the traditional Rivlin-Saunders method.
