摘要

Aromatic Polyimides find widespread technological applications due to their unique combination of low dielectric constant, chemical resistance and high thermal and thermooxidative stability. Polyimides (PIs) can be conveniently prepared by the condensation polymerization of dianhydrides with diamines. In general, polyimides are synthesized by a multistep method through a polyamic acid or a polyamic ester intermediate. Direct one-step high temperature polycondensation is an alternative route to the preparation of PI when they are soluble in organic solvents.
