| 摘要 |
Liquid crystalline polyesteretherimides are prepared by a transesterification reaction involving terephthalic acid and acylated derivatives of 4-hydroxybenzoic acid and of certain bisimidodiphenols, or from the free bisimidodiphenol and aryl esters of the acids. In addition to being liquid crystalline, the polyesteretherimides are crystalline in the solid state and have relatively high glass transition temperatures.
