Comparative Study of Polyimide Synthesis Methods

Three synthesis methods of polyimide are summarized in this paper,namely melt polycondensation,solution polycondensation and interfacial polycondensation.In addition,the three methods of preparing polyimide were compared and commented.And it shows that the solution polycondensation method is likely the most important and widely used way to synthesize aromatic polyimide up to now.
