“…A typical example for polymer P1 is given as follows [13]. To a 100 ml three-neck round-bottom flask equipped with a stirrer, a Dean-Stark trap and condenser, and a nitrogen inlet were added compound 6 (0.592 g and 1.0 mmol) and 4,4 0 -dihydroxybenzophenone (0.214 g and 1.0 mmol).…”

“…There have been a limited number of reports describing PAEs in which the activating group is located in a pendant position. Some notable examples include the recent synthesis of poly(biphenylene oxide)s containing pendant trifluoromethyl groups42, 43 and the synthesis of PAEs with pendant benzoyl moieties reported independently by the groups of Cassidy44 and Kricheldorf 45, 46. The synthesis and characterization of nitrile containing poly(phenylene oxide), (PPO) via the reaction of 2,6‐difluorobenzonitrile with various bisphenols or silylated bisphenols has also been described 47–50.…”

A series of poly(arylene ether)s, (PAEs), carrying a pendant diphenyl phosphoryl group were prepared via the nucleophilic aromatic substitution (NAS) reactions of 3,5‐difluorotriphenylphosphine oxide, 6. The difluoro monomer 6 was synthesized via two‐step reaction sequence and subsequently characterized by 1H, 13C, 19F, and 31P NMR spectroscopy, GC/MS, and elemental analysis. The reactivity of the electrophilic sites in 6, activated by only a diphenylphosphoryl group located in the meta‐position, in 6 was probed via NMR spectroscopy and model reactions and was determined to be sufficient to undergo typical NAS reactions. High molecular weight, amorphous, organic soluble poly(arylene ether)s, bearing a pendant diphenylphosphoryl group, were prepared via the reaction of 6 with a variety of bis‐phenols under typical NAS conditions. The poly(arylene ether)s were characterized for structure via the use of 1H, 13C, and 31P NMR spectroscopy while their thermal properties were evaluated using DSC and TGA analysis. The glass transition temperatures (Tg) of the synthesized PAEs ranged from 143 to 175 °C, while their 5% weight loss temperatures ranged from 467 to 510 °C under nitrogen and from 470 to 526 °C in air. © 2011 Wiley Periodicals, Inc.
