Method of preparing oligomeric brominous xylylene bisphenol ethers

摘要

An improved process for the preparation of oligomeric bromine containing xylylene bisphenol ethers is described wherein xylylene dichlorides and/or dibromides are reacted with bisphenols at 85 DEG to 160 DEG C. in the presence of an alkaline compound or employing the bisphenol in the form of an alkali salt wherein the reaction is conducted employing a ketone as solvent.
