Abstract
An aryl composition includes aryl ether oligomers. These compositions may be prepared by reaction of one or more dihalobenzenes with one or more dihydroxybenzenes by an Ullman ether reaction. The oligomers may have two or more benzene rings and include terminal halogen, e.g., bromine (Br), or hydroxyl (OH) groups. These oligomers may be brominated to form flame retardant compositions for thermoplastic polymers.
