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 4,4Π-difluorobenzophenone in N-cyclohexylpyrrolidinone containing anhydrous potassium carbonate. The polymers exhibited high glass transition temperature
## Abstract Novel poly(arylene ether)s with a rigid and zigzag 4,4β³β__o__βterphenyldiyl structure, introduced into the polymer backbone were synthesized by nucleophilic displacement reaction of 4,4β³βdihydroxyβ__o__βterphenyl with several activated aromatic dihalides in virtually quantitative yields
Poly(arylene ether)s ( 3), (4) containing pendant benzoyl groups as precursors for novel polyxanthenes ( 7), (8) were prepared by nucleophilic substitution reaction of 2,5-difluoro-4-benzoylbenzophenone ( 1) or 2,5-difluoro-4-(4-dodecylbenzoyl)-4dodecylbenzophenone ( 2) with hydroquinone derivatives
