用平均场理论研究了半柔性高分子链在低分子量液晶溶剂中的构象。我们考虑到刚度和部分取向有序的聚合物。作为一个结果的各向异性的耦合之间的聚合物和聚碳酸酯，我们预测一个不连续的（或连续的）相变从凝聚棒状构象的聚合物链的溶胀之一，这取决于聚合物的刚度。我们还讨论了聚合物链段之间的相互作用的影响。
Conformations of a single semiflexible polymer chain dissolved in a low-molecular-weight liquid crystalline solvent (nematogen) are examined by using a mean field theory. We take into account a stiffness and partial orientational ordering of the polymer. As a result of an anisotropic coupling between the polymer and nematogen, we predict a discontinuous (or continuous) phase transition from a condensed-rodlike conformation to a swollen one of the polymer chain, depending on the stiffness of the polymer. We also discuss the effects of the nematic interaction between polymer segments.
