## Description

- description: 'We are conducting research aimed at the practical application of sulfonated
    PPSU, a hydrocarbon electrolyte, as a non-fluorine electrolyte. In this study,
    we report the synthesis and properties of sulfonated PPSU with high ion exchange
    capacity (IEC) (calculated value: 5.55meq/g), which has four sulfo groups per
    repeating unit of PPSU. SPPSU (2S), which has two sulfo groups per repeating unit
    of PPSU (IEC=3.57meq/g), was obtained by sulfonation of bis(4-fluorophenyl)sulfone
    using 30% Oleum. Next, polymerization was performed by condensation reaction of
    sulfonated bis(4-fluorophenyl)sulfone (SFPS) and 4,4''-biphenol (BP). Furthermore,
    by sulfonating these polymers in sulfuric acid, SPPSU (4S) having four sulfo groups
    per repeating unit (IEC=5.55meq/g) was synthesized. The molecular weight of SPPSU(4S)
    was 130,304 – 303,203. Depending on the sulfonation conditions using SPPSU(2S)
    polymer and sulfuric acid, the viscosity of SPPSU(4S) was 30 to 270 mP·s, which
    was higher than that of Nafion (D520CS), which was 10 to 40 mPa·s. In addition,
    the tensile strength, tensile elongation, and flexural modulus of SPPSU (4S) were
    22 MPa, 251%, and 296 MPa. Compared to Nafion 212, it exhibited high tensile strength
    and flexural modulus while having similar tensile elongation properties. Furthermore,
    the conductivity of SPPSU (4S) was 11.3 mS/cm at 120°C and RH 10%. This value
    was approximately 4 times higher than the conductivity of Nafion212 (3.2 mS/cm)
    under the same conditions.'
