我们提出了一种基于类固体和类液体自由度分离并考虑网络结构的冻结不均匀性的随机交联聚合物网络的唯象理论。给出了该模型统计力学的完整解，并计算了良溶剂和ϑ溶剂中中性凝胶的单体密度相关函数。将理论散射曲线与小角中子散射和光散射实验的结果进行比较，并提出了我们理论的新实验测试。
We present a phenomenological theory of randomly cross-linked polymer networks based on the separation of solid-like and liquid-like degrees of freedom and taking into account the frozen inhomogeneity of network structure. The complete solution of the statistical mechanics of this model is given, and the monomer density correlation functions are calculated for neutral gels in good and ϑ solvents. The theoretical scattering curves are compared to the results of small angle neutron scattering and light scattering experiments, and new experimental tests of our theory are proposed.
