Hydroxy-terminated arylene ethers, and method for making |
摘要 |
A method is provided for making certain hydroxy-terminated arylene ethers useful as spacers in liquid crystalline polyesters. There is initially formed a dicarbonyl adduct from a dihydroxyaromatic compound, such as hydroquinone and a haloarylcarbonyl compound. The adduct formed is oxidized to the corresponding diester. Hydrolysis of the diester provides the hydroxy-terminated arylene ether.
