The Determination of Solubility Parameter of Polymer by Means of Swelling Kinetics

Abstract

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.
