Abstract
Theoretical equation to predict kinetic absorption behaviors of swellable polymers was developed on the basis of Darcy’s law The absorption pressure was derived on the model of binary interaction between polymer and solvent The key variables considered in the equation were the absorption sites of polymer the concentration of solvent and the binding order of solvent molecules The equation was tested with the experimental data of PET in chloroform/hexane mixed solvent from literature The model equation can simulate the kinetic absorption behaviors and also help to rationalize the experimental results
