Poly(arylene ether)s ( 3) containing pendant benzoyl groups were prepared by the aromatic substitution reaction of 2,5-difluoro-4-benzoylbenzophenone ( 2) with hydroquinone (1a) and methylhydroquinone (1b) in the presence of potassium carbonate in N,N-dimethylacetamide. The polycondensation proceede
A series of novel poly(arylene ether ketone)s were synthesized from the reaction of hydroquinone and 4-(4-hydroxyphenyl)-2,3-phthalazin-1-one with 4,4Ј-difluorobenzophenone in N-cyclohexylpyrrolidinone containing anhydrous potassium carbonate. The polymers exhibited high glass transition temperature
