Abstract: From earlier experiments it was observed that the reactions of aryl fluoride functional aryl ether ketone oligomers (PEK) with m-aminophenol lead to poor levels of amine incorporation because of side-reactions. In this article, a method is presented to protect the m-aminophenol by converting it into a triarylimine group. This protected m-aminophenol was used together with 4-fluoro,4'-hydroxybenzophenone in a typical poly(aryl ether) synthesis. PEKs of different molecular weights were synthesized with number average molecular weights M(n)) of 2600, 4500, and 5400 g/mol. The deprotection of the triarylimine chain end was carried out by an acid treatment to afford a monofunctional aromatic amine end group, amenable towards copolymerization.
