文摘
- •
Radical terpolymerization of chlorotrifluoroethylene and vinyl ethers.
- •
The chemical modification of these terpolymers yielded fluorofunctional terpolymers containing triazole groups.
- •
Original blend membranes from these terpolymers and sulfonated PEEK.
- •
The crosslinking of such terpolymers by telechelic diamines via the cyclocarbonate/amine reactions.
- •
The conductivities of the resulting membranes reached 4.3 mS cm−1 at 140 °C and at low RH.
