摘要翻译:
我们考虑单分散聚合物溶液的渗透压、回转半径、流体动力学半径和端到端距离的前几个维里系数。我们确定了相应的双参数模型函数,这些模型函数参数化了良好溶剂和理想链行为之间的交叉。这些结果使我们能够预测在θ点以上较大温度范围内稀相区的渗透压和聚合物尺寸。

英文摘要:
We consider the first few virial coefficients of the osmotic pressure, the radius of gyration, the hydrodynamic radius, and the end-to-end distance for a monodisperse polymer solution. We determine the corresponding two-parameter model functions which parametrize the crossover between the good-solvent and the ideal-chain behavior. These results allow us to predict the osmotic pressure and the polymer size in the dilute regime in a large temperature region above the theta-point.
