Ion exchange fluorocarbon resin membrane |
| 摘要 |
An ion exchange fluorocarbon resin membrane having a storage modulus (JIS K-7244), when substituted with tributyl ammonium ions, at a temperature of not less than Tc represented by the following general equations (1-1) to (1-3) of 0.8x10<SUP>6 </SUP>Pa or more, and a heat of crystal fusion at 270 to 350° C. of 1 J/g or less: <?in-line-formulae description="In-line Formulae" end="lead"?>Tc (° C.)=55+Tg (EW<750) (1-1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Tc (° C.)=0.444xEW-278+Tg (750<=EW<930) (1-2)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Tc (° C.)=135+Tg (EW>=930) (1-3)<?in-line-formulae description="In-line Formulae" end="tail"?> where Tg designates the peak temperature of loss tangent in the dynamic viscoelasticity measure-ment of the ion exchange fluorocarbon resin membrane (having SO<SUB>3</SUB>H as the ends of the side chains). |
