Aromatic polyester, process for production thereof and film, fiber and other shaped articles therefrom. |
摘要 |
<p>A novel, substantially linear aromatic polyester comprising 6,6 min -(ethylenedioxy)di-2-naphthoic acid as a main acid component and an aliphatic glycol having 2 to 10 carbon atoms in the main chain of the glycol as a main glycol component. The aromatic polyester is prepared by condensing an ethylene glycol diester of 6,6 min -(ethylenedioxy)di-2-naphthoic acid, or a mixture of a major proportion of said naphthoate with a dicarboxylic acid, a diol, a hydroxycarboxylic acid or an ester-forming derivative thereof, at an elevated temperature. The aromatic polyester has excellent mechanical properties such as strengtil and Young's modulus.</p> |
