## Abstract A series of controlled molecular weight poly(aryl ether sulfone) oligomers with benzophenone moieties at the chain termini were prepared. The two carbonyl groups at the chain ends were converted to ethynyl groups by using trimethylsilyldiazomethane/BuLi in tetrahydrofuran. Reactions of
Crosslinkable alkyl-substituted poly(aryl ether ketone)s (PEKs) bearing a styryl group at both chain ends were synthesized by nucleophilic substitution reaction of 1,l'-(p-phenylenedioxy)bis[2-methy l-4-( 4-fluorobenzoyl) benzene] with an excess aromatic diol in the presence of a base, followed by t
