“…In the graft copolymers with poly(vinyl phosphoric)acid [41], the well-separated poly(phosphoric) acid side chains along stiff and hydrophobic PSF main chains could produced membranes with interesting water uptake. The solubility of polyethersulfone with a bis(4-carboxyphenyl)phenyl phosphine oxide in main chain [54] were readily soluble at room temperature in polar, aprotic solvents, such as N-methyl-2-pyrrolidone, dimethylacetamide, dimethylformamide, and dimethyl sulfoxide. They were also soluble in chloroalkylenes and in tetrahydrofuran at elevated temperatures.…”

“…First, toluene was added to the reaction mixture and azeotropic distillation was continued until water that formed during the reaction was removed from the reaction mixture. 12 In the later stage, temperature was increased to 160 • C and polymerization was progressed for required time. All the crude polymers were purified by reprecipitation from THF in hexane.…”

Synthesis of phosphorus containing polyethers and their lithium-ion conductivities for the potential use as solid polymer electrolyte (SPE) in high-energy density lithium-ion batteries have been described. Co-polymerization of butyl bis(hydroxymethyl)phosphine oxide with three different dibromo monomers were carried out to produce three novel phosphorous containing polyethers (P1-P3). These polymers were obtained via nucleophilic substitution reactions and were characterized by 1 H, 31 P NMR spectral data and gel permeation chromatography. SPEs were prepared using polyethers (P1 and P2) with various amounts of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). The lithium-ion conductivity of SPE2 containing 40 wt% of LiTFSI was 2.1 × 10 −5 S cm −1 at room temperature and 3.7 × 10 −4 S cm −1 at 80 • C.

“…4 Although traditional PEKs such as PEEK and PEKK show excellent performance, their poor solubility in common organic solvents and their high melting temperatures make them difficult to process and fabricate. To overcome these limitations, several approaches have been investigated to improve the solubility and processability of PEKs without significantly weakening their desired properties, such as the introduction of flexible linkages, 5 –7 bulky units, 8 –11 alicyclic moieties, 12 –15 and noncoplanar structures 16 –18 into the main chains of PEKs. Incorporating pendant groups into the PEK backbones is also an effective structural modification method.…”

4-(4-Diphenylphosphino)phenyl-2,6-bis(4-hydroxyphenyl)pyridine, as a new bisphenol monomer, was prepared from 4-(diphenylphosphino)benzaldehyde and 4-hydroxyacetophenone and used in the preparation of several aromatic poly(ether ketone)s (PEKs) containing 2,6-diphenylpyridyl units and diphenylphosphinophenyl pendant groups via a nucleophilic aromatic substitution polycondensation with difluorinated aromatic ketones. The polycondensation proceeded quantitatively in tetramethylene sulfone in the presence of anhydrous potassium carbonate and afforded the polymers with high molecular weights. The resulting PEKs are amorphous and exhibit high glass transition temperatures of 209–255°C and 5% weight loss temperatures of 536–554°C with char yields of 57–62% at 800°C in nitrogen. Their high char yields and good limited oxygen index values ranging from 39 to 43 indicated these polymers exhibited good thermal stability and flame-retardant property. All new PEKs were soluble in common organic solvents such as N-methyl-2-pyrrolidone, N,N-dimethylacetamide, and chloroform and could form tough, flexible, and strong films with tensile strengths of 74.6–86.8 MPa, tensile moduli of 2.9–3.6 GPa, and elongations at break of 5–9%.
