Naphthyl and ether chain-containing carboxyl derivatives |
摘要 |
New aromatic dicarboxylic acids, 1,4- or 2,6-Bis(p-carboxyphenoxy)naphthyl is prepared by the reaction of p-fluorobenzonitrile with 1,4-naphthalenediol, followed by hydrolysis. Wholly aromatic polyamides having superior solubility in a variety of organic solvents and have good thermal stability can be obtained by reacting the new aromatic dicarboxylic acids with aromatic diamines. Transparent, tough and flexible films of these polyamides can be cast from the solutions thereof and these polyamides are easily processable high-performance polymer materials.
