由各向同性溶剂产生的线状弹性体的膨胀较早被预测（Macromolecules 25,445(1992)）比传统弹性体的膨胀更为复杂。我们在这里扩展到溶剂的膨胀，在纯弹性体的纯相区域中，溶剂具有向列-各向同性转变。相图与第一个病例在性质上有所不同，但仍然具有初始研究中报道的三相点和凝胶-凝胶双相间隙的新特征。当交叉耦合强于自耦合时我们有一个共沸点。
The swelling of a nematogenic elastomer by an isotropic solvent was earlier predicted (Macromolecules 25, 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.
