## Abstract Novel poly(arylene ether)s with a rigid and zigzag 4,4โณโ__o__โterphenyldiyl structure, introduced into the polymer backbone were synthesized by nucleophilic displacement reaction of 4,4โณโdihydroxyโ__o__โterphenyl with several activated aromatic dihalides in virtually quantitative yields
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 4,4ะ-difluorobenzophenone in N-cyclohexylpyrrolidinone containing anhydrous potassium carbonate. The polymers exhibited high glass transition temperature
## Abstract Methylโsubstituted or unsubstituted aromatic dicarboxylic acids and diamines containing ether and sulfone linkages between phenylene units were used alone or in combination with __p__โphenylenediamine, __m__โphenylenediamine, terephthalic acid, and isophthalic acid to prepare flexible o
