Method for producing a liquid crystalline polyester and the liquid crystalline polyester |
| 摘要 |
The object is to provide liquid crystalline polyester which gives molded articles without generating acetic acid gas, and a method for producing the liquid crystalline polyester. This object is achieved by a method for producing a liquid crystalline polyester comprising melt-polymerizing aromatic hydroxycarboxylic acid represented by the formula (I), aromatic diol represented by the formula (II), and aromatic dicarboxylic acid represented by the formula (III) with using a diaryl carbonate represented by the formula (IV). <?in-line-formulae description="In-line Formulae" end="lead"?>HO-R<SUB>1</SUB>-COOH (I)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>HO-R<SUB>2</SUB>-OH (II)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>HOOC-R<SUB>3</SUB>-COOH (III)<?in-line-formulae description="In-line Formulae" end="tail"?>
