溶胀动力学法测定高聚物溶度参数

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

用溶胀性能测定仪，以溶胀动力学方法成功地测定了线型及交联高聚物的溶度参数。此方法较传统的特性粘数极大值法及平衡溶胀度法方便、省时、省力，易于推广。

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(Q method), the method is much better and worth getting applications widely because of convenience, time and energy-saving.
