Soluble Polyamides and Polyimides Functionalized with Benzo-15-Crown-5-Pendant Groups 

 -  Macromol. Rapid Commun., 25, p.592-597, 2004 .
<br/><br/> 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 filmforming ability.
