Abstract: A novel crosslinkable fluorinated poly(ether ether ketone) with acetylenylbenzene end groups was prepared by solution condensation. The chemical structure of such polymer was confirmed by FTIR and 1HNMR. The crosslinking behavior and thermal stability were investigated by DSC and TGA respectively. The DSC thermogram for the first heating run shows a glass transition of 6F-PEEK at about 395 K and a exothermic peak correspongding to the self-crosslinking reaction of fluorinated poly(ether ether ketong) at about 700 K. For the second heating run, the exothermic peak disappered and the glass transition shifted to a higher temperature. The crosslinked polymer shown excelent thermal stability and solvent-resistence. The temperature for 5% weight loss was 774 K and the self-crosslinked polymer was no more disolved by polar solvents, which disolved in before crosslinking, such as DMF, DMAc and NMP. This kind of polymer may be a potential material used as electro-optical devices.

Key words: Poly(ether ether ketone), Fluorinated polymer, Cross-linking
