## 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
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
Cyclic(arylene disulfide) and polycyclic(arylene sulfide) oligomers were synthesized by catalytic oxidation of arylenedithiols or arylenetrithiols with oxygen in the presence of a copper-amine catalyst. These cyclic(arylene sulfide) oligomers can undergo free radical ring-opening polymerization at a
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
