Caused by the introduction of Gibbs distribution into the Flory-Huggins theory, the partition function and the thermodynamic description depicted their dependence on temperature well. In the present study, we applied the theory to calculate polymer solubility parameters. The polymer solubility parameters predicted by our theory are well consistent with the experiment values.展开更多
