基团贡献法研究环型聚苯乙烯稀溶液流体力学参数
摘要:
首次采用基团贡献法, 根据内聚能、摩尔体积、摩尔吸引常数和临界特性粘数等分别计算并通过实验数据验证了环型和线型聚苯乙烯的溶度参数, 特性粘数、摩尔极限粘数函数、临界分子量和Mark-Houwink参数, 详细地讨论了计算大环高分子的K_(θ,r)值所取用的临界分子量应具有的理论意义。

Study on Hydrodynamic Parameters of Ring-Shaped Polystyrene in Dilute Solution by the Method of Group Contributions
Abstract:
The group contribution mothod has been used to calculate the values of solubility parameter, intrinsic viscosity, Mark-Houwink parameters of ring-and linear shaped polystyrene according to cohesive energy, molar volume, molar attraction constant. All these calculating results were also experimentally demonstrated. Futhermore, the theoretical significance of the value of critical molecular weight used calculating the K_(θ,r) of ring-shaped polymer is detaily discussed.
