Poly(arylene ether)s, poly(arylene thioether)s, and poly(arylene sulfone)s derived from a dihydroxy(imidoarylene) monomer

Synthesis of Functional Aromatic Multisulfonyl Chlorides and Their Masked Precursors

“…Scheme describes the synthesis of 6 and 8 via the Newman−Kwart rearrangement 7 of the corresponding O -aryl isomers 5 and 7 . Several methods are available for the esterification involved in the synthesis of O -(aryl)- N , N ‘-dialkylthiocarbamate by reacting N , N ‘-dialkylthiocarbamoyl chloride with the corresponding phenolic precursors in the presence of a base such as DMF/NaH, 20a-c DMF/NaOH/K 2 CO 3 /PTC (phase transfer catalyst), KOH/MeOH, and quinoline …”

Synthesis and characterization of soluble, fluorescent poly(arylene ether)s, poly(arylene thioether)s, and poly(arylene sulfone)s containing 1,3,5‐triphenylbenzene segments

“…In our earlier studies,10 we demonstrated the preparation of high‐ T g and soluble poly(sulfone)s by the oxidation of poly(arylene thioether)s containing a pendent imido group. Similarly, in this study new poly(sulfone)s with pendent phenyl groups were readily obtained from poly(arylene thioether)s with hydrogen peroxide in 95–97% formic acid.…”

Synthesis and characterization of cross‐linkable poly(phthalazinone ether ketone)s

“…The polymerization has been confirmed to proceed via a novel NC coupling reaction as evidenced by spectroscopic studies 6, 7. Thereafter, many phthalazinone‐containing high‐performance polymers, such as poly(phthalazinone ether)s,8–13 polyamides, and polyimides14 with good solubility and excellent thermal stability have been reported. The poly(phthalazinone ether)s, represented by poly (phthalazinone ether ketone)s and poly(phthalazinone ether sulfone)s, are a new class of PAEs with excellent thermooxidative stability, high glass transition temperature ( T g ), good solubility, and outstanding mechanical properties.…”
