“…In the past decades, many efforts have been made to improve the thermal stability, mechanical performance, and electrical properties of PAE. − Compared with the traditional PAEs, poly(aryl ether sulfone)s (PAESs) exhibited better thermal resistance. Ling et al successfully synthesized a phenolphthalein poly(ether sulfone) containing isopropyl by the S N 2 aromatic nucleophilic condensation reaction; the T g was increased to 202 °C.…”

A series of poly(aryl ether sulfone)s including bis-phthalazinone moieties (PBPES-Ps) that displayed improved heat resistance were obtained through condensation polymerization. The structures of the PBPES-Ps were investigated by FT-IR, 1 H NMR, and XRD. The heat resistance of the PBPES-Ps can be regulated according to the monomer contents in the polymerization. The glass transition temperature (T g ) of PBPES-Ps was 280−349 °C and the 5% mass loss temperature was up to 514 °C. The PBPES-Ps had high mechanical and thermo-mechanical characteristics, i.e., the storage modulus and the tensile strength of PBPES-Ps were as high as 1.81 GPa and 95.3 MPa, respectively. Furthermore, the storage modulus retention reached 76.5% at 220 °C. With the introduction of the 4,4′-di(4′-1(2H)-phthalazinone)-1,1′-biphenyl (BPBN), both the dielectric loss (D f ) and dielectric constant (D k ) of PBPES-Ps decreased, and the lowest values of D f and D k were 0.0061 and 2.95 at 1 GHz, respectively. The PBPES-Ps' hydrophobicity declined with the increasing BPBN content. In addition, the PBPES-Ps were soluble in conventional solvents like Nmethyl-2-pyrrolidinone as well as 1,1,2,2-tetrachloroethane.

“…Poly(aryl ethers)s (PAEs) possess high T g , outstanding thermomechanical performance, toughness, chemical resistance, and good wear resistance. , In the past, some investigators have worked on PAE dielectric polymers with the aim of obtaining excellent high-temperature energy-storage properties. For instance, Liu et al synthesized poly(arylene ether sulfone) (DPAES) containing propylene side groups with a U e of 1.16 J/cm 3 at 150 °C.…”
