本文给出了各向同性网络在极性溶剂中的溶胀平衡理论。它是基于Flory晶格模型，适用于柔性聚合物与热致液晶的混合物。溶胀度在溶剂的各向同性到非均质转变温度处表现出异常。低于该温度，网络连续收缩至几乎不超过干燥状态的尺寸的尺寸。
Abstract A theory of swelling equilibria of isotropic networks in nematic solvents is given. It is based on the Flory lattice model adapted for mixtures of flexible polymers with thermotropic nematic liquid crystals. The degree of swelling exhibits an anomaly at the isotropic to nematic transition temperature of the solvent. Below this temperature the network shrinks continuously to a size hardly exceeding the dimensions of the dry state.
