Abstract: This paper was succeeded in the determination of solubility parameter of both linear and network polymer by means of swelling kinetics, which has the following procedures:(1)determine the swelling rate in the solvents with different solubility parameters(δ1);(2)draw a curve of swelling rate against δ1;(3)take the δ1 at the peak value of the curve as the polymeric solubility parameter δ2.In comparison with the classical methods of maximum intrinsic viscosity(MIV) and swelling equilibrium(Qmethod), the method is much better and worth getting applications widely because of convenience, time and energy-saving.
