Abstract

Summary: A new diamine monomer containing a crown ether was made to react with commercial diacid chlorides and dianhydrides to yield new aromatic polyamides and polyimides. The crown ether moiety was introduced as a pendant group so that the polymers showed enhanced solubility in organic solvents, good thermal properties (high transition temperatures and high thermal stability), and good film‐forming ability.

The new aromatic polyamides and polyimides bearing a benzo‐15‐crown‐5‐pendant group synthesized here.

## Abstract Acylation reactions of benzocrown ethers with __N__‐phthalimido‐protected derivatives of β‐alanine and 11‐aminoundecanoic acid, respectively, were investigated in acid catalysis by using the Eaton reagent. Deprotection of the obtained compounds by hydrazinolysis afforded derivatives wit
