<jats:title>Abstract</jats:title><jats:p>The swelling of a nematogenic elastomer by an isotropic solvent was earlier predicted (<jats:italic>Macromolecules</jats:italic> <jats:bold>25</jats:bold>, 445 (1992)) to be more complex than that of a classical elastomer. We extend here to the swelling by solvents having a nematic‐isotropic transition in the pure phase in the region of that of the pure elastomer. The phase diagrams are qualitatively different from the first case, but still with the novel features of a triple point and a gel‐gel biphasic gap reported in the initial study. Where the cross‐coupling is stronger than the self‐couplings we have an azeotropic point.</jats:p>
