超临界流体技术及其在聚合物纯化中的应用

SUPERCRITICAL FLUID TECHNIQUE AND ITS APPLICATION IN POLYMER PURIFICATION

综述了超临界流体（ＳＣＦ）的性质及其技术发展情况。阐述了建立ＳＣＦ－聚合物类多元体系溶解度数学模型及扩散系数数学模型的方法，并对ＳＣＦ萃取技术在聚合物纯化中的应用作了例解。

The development of supercritical fluid (SCF) technique was reviewed with 43 references. The methods of building mathematical models for calculating the solubilities were described.Two examples of polymer purification with SCF were illustrated.
